1. Find the area of following rectangles whose length and breadth are as follows :

Question 1.
9 m and 7 m
Solution:
Length of rectangle = 9 m
Breadth of rectangle = 7 m
Area of rectangle = Length × Breadth
= 9 m × 7 m
= 63 m²

Question 2.
85 cm and 76 cm

Area of verandah = Length × Breadth
= 52 m × 32 m
=1664 m²

Pankaj :
Side of square verandah = 41 m
Area of square verandah = Side × side
= 41 m × 41 m
= 1681 m²
Area of verandah of Pankaj’s home is bigger by
= 1681 m² – 1664 m²
= 17 m²

Question 8.
Roof of Amarjeet’s home is of length 9 m and breadth 6 m. There is a leakage of water from the roof. He wants to fix tiles of size 30 cm long and 20 cm wide for plugging the leakage. How many tiles does he need ?
Solution:
Length of the roof = 9 m
= 9 ² 100 cm
= 900 cm
Breadth of the roof = 6 m
= 6 ² 100 cm
= 600 cm
Area of the roof = Length × Breadth
= 900 cm × 600 cm
= 540000 cm²
Length of each tile = 30 cm
Breadth of each tile = 20 cm
Area of each tile = Length × Breadth
= 30 cm × 20 cm
= 600 cm²
Area of the roof
Number of tiles = \(\frac{\text { Area of the roof }}{\text { Area of each tile }}\)
= \(\frac{540000}{600}\) = \(\frac{900 \times 600}{600}\)
= 900.

PSEB Solutions for Class 5 Maths Chapter 8 Perimeter and Area Ex 8.1

1. Find the perimeter :

Question 1.

Solution:
Perimeter of a rectangle = Length + Breadth + Length + Breadth
= 2 (Length + Breadth)
= 2 (8 m + 3 m)
= 2 × 11 m
= 22 m.

Question 2.

Solution:
Perimeter of a square = side + side + side + side
= 4 × side
= 4 × 5 cm
= 20 cm.

2. Find the perimeter of the rectangle whose length and breadth are as follows :

Question 1.
3 cm, 2 cm
Solution:
Length of the rectangle = 3 cm
Breadth of the rectangle = 2 cm
Perimeter of the rectangle = 2 (Length + Breadth)
= 2 (3 cm + 2 cm)
= 2 × 5 cm
= 10 cm.

Question 2.
12 m, 10 m
Solution:
Length of the rectangle = 12 m
Breadth of the rectangle = 10 m
Perimeter of the rectangle = 2 (Length + Breadth)
= 2 (12 m + 10 m)
= 2 × 22 m
= 44 m.

Question 3.
15 cm, 8 cm.
Solution:
Length of the rectangle = 15 cm
Breadth of the rectangle = 8 cm
Perimeter of the rectangle = 2 (Length + Breadth)

Solution:
Side of the square = 4 cm
Perimeter of the square = 4 × side
= 4 × 4 cm
= 16 cm.

Question 2.
8 cm
Solution:
Side of the square = 8 cm
Perimeter of the square = 4 × side
= 4 × 8 cm
= 32 cm.

Question 3.

Number of bricks in the trolly
= \(\frac{\text { Volume of trolly }}{\text { Volume of each brick }}\)
= \(\frac{400 \times 200 \times 100}{20 \times 10 \times 6}\)
= \(\frac{20 \times 20 \times 50}{3}\) = \(\frac{20000}{3}\)
= 6666 (Approx)

Solution:
Jashan :
Length of the tiffin box = 15 cm
Breadth of the tiffin box = 10 cm
Height of the tiffin box = 8 cm
Volume of the tiffin box = Length × Breadth × Height
= 15 cm × 10 cm × 8 cm
= 1200 cm³

Gurwinder :
Length of the tiffin box = 12 cm
Breadth of the tiffin box = 10 cm
Height of the tiffin box = 10 cm
Volume of the tiffin box = Length × Breadth × Height
= 12 cm × 10 cm × 10 cm
= 1200 cm³
Their tiffin boxes have equal volumes.

Question 8.
Find the volume of 25 cuboidal boxes with dimensions 12 cm long, 9 cm wide and 6 cm high each.
Solution:
Length of the cuboidal box =12 cm
Breadth of the cuboidal box = 9 cm
Height of the cuboidal box = 6 cm
Volume of the cuboidal box = Length × Breadth × Height
= 12 cm × 9 cm × 6 cm
= 648 cm³
Volume of 25 cuboidal boxes
= 648 × 25 cm³
= 16200 cm³

Question 9.
There are two types of powder boxes available in the market. One is of cubical shape with side 8 cm and other is of cuboidal shape with length 15 cm, breadth 8 cm and height 4 cm. Which box has more powder and how much? If both have same prices then which box will you prefer?
Solution:
Side of the cubical box = 8 cm
Volume of the cubical box = side x side x side
= 8 cm × 8 cm × 8 cm
= 512 cm³
Length of the cuboidal box = 15 cm
Breadth of the cuboidal box = 8 cm
Height of the cuboidal box = 4 cm
Volume of the cuboidal box = Length × Breadth × Height
= 15 cm × 8 cm × 4 cm
= 480 cm³
Cubical box has more powder
= 512 cm³ – 480 cm³
= 32 cm³
I will prefer cubical box.

Question 10.
How many bricks of size 24 cm long, 12 cm wide and 8 cm thick are required for* making a wall of 12 m long, 3 m high and 24 cm thick?
Solution:
Length of the wall = 12 m
= 12 × 100 cm
= 1200 cm
Height of the wall = 3 m
= 3 × 100 cm
= 300 cm
Breadth of the wall = 24 cm
Volume of the wall = Length × Breadth × Height
= 1200 cm × 24 cm × 300 cm
= 8640000 cm³
Length of each brick = 24 cm
Breadth of each brick = 12 cm
Height of each brick = 8 cm
Volume of each brick = Length × Breadth × Height
= 24 cm × 12 cm × 8 cm
= 2304 cm³
Number of bricks required
= \(\frac{8640000 \mathrm{~cm}^{3}}{2304 \mathrm{~cm}^{3}}\)
= 3750 bricks.

Question 11.
The length, breadth and height of a biscuit packet is 15 cm, 9 cm and 6 cm respectively. If a packet has 30 biscuits then Bind the volume of each biscuit.
Solution:
Length of the packet = 15 cm
Breadth of the packet = 9 cm
Height of the packet = 6 cm
Volume of the packet = Length × Breadth× Height
= 15 cm × 9 cm × 6 cm
= 810 cm³
Total number of biscuits in the packet = 30
Volume of each biscuit = \(\frac{810 \mathrm{~cm}^{3}}{30}\)
= 27 cm³

Question 12.
One trolley is full of bricks. It is 4 m long, 2 m wide and 60 cm deep. One brick is of size 20 cm x 10 cm x 6 cm. How many bricks are there in the trolley ?
Solution:
Length of the trolley
= 4m = 4 × 100 cm = 400 cm
Breadth of the trolley
= 2 m = 2 × 100 cm = 200 cm
Depth (Height) of the trolley = 60 cm
Volume of the trolley = Length × Breadth × Depth
= 400 cm × 200 cm × 60 cm
= 4800000 cm³
Length of the brick = 20 cm
Breadth of the brick = 10 cm
Height of the brick = 6 cm
Volume of the brick = Length × Breadth × Height
= 20 cm × 10 cm × 6 cm
= 1200 cm³
Number of bricks in the trolley
= \(\frac{4800000}{1200}\) cm³
= 4000.
