Answer 1

Question 4:

• Find the area of a rectangular playground which is 36 m long and 24 m wide.

Given:

• Length of rectangle, l = 36m.
• Breadth of rectangle, b = 24m.

Exigency to find:

• Area of rectangular playground.

Solution:

We know that, if we are given with the length of rectangle and breadth of rectangle, we have the required formula, that is,

• Area of rectangle = l × b.

« Substituting the given values in the formula,

→ Area of rectangle = 36 × 24

→ Area of rectangle = 864.

∴ The area of rectangular playground is 864m².

Question 5:

• One side of a square tile is 15.6 cm. Find the area of the tile.

Given:

• Side of a square tile, a = 15.6cm.

Exigency to find:

• Area of the square tile.

Solution:

We know that, if we are given with the side of square, we have the required formula, that is,

• Area of square = (side)².

« Substituting the given values in the formula,

→ Area of square = (15.6)²

→ Area of square = 15.6 × 15.6

→ Area of square = 243.36.

∴ The area of square tile is 243.36cm².

Answer 2

Question No 5 :-

➦ One side of a square tile is 15.6 cm. Find the area of the tile.

Given :-

• One side of a square is 15.6 cm.

To Find :-

• What is the area of the tile.

Formula Used :-

➲ Area of Square = (Side)²

Solution :-

Given :

• Side = 15.6 cm

According to the question by using the formula we get,

↦ Area of the tile = (15.6)²
