Answer 1

$\huge{\tt{\red{❥}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$

$\pink\longrightarrow$ Perimeter of a square = 40 cm

$\pink\longrightarrow$ Number of sides of a square = 4

$\pink\longrightarrow$ length of each side of a square = 40/4 = 10cm

$\pink\longrightarrow$ area = 10cm × 10cm

$\pink\longrightarrow$ 100cm²

Answer 2

• The area = 100 sq.cm

Given :-

• The perimeter of a square is 40 cm.

To find :-

• Its area.

Step-by-step explanation :-

A square has 4 sides.

All its sides are equal.

Perimeter of a square = 4 × Side.

We know the perimeter.

So, each side of this square = 40 cm ÷ 4 = 10 cm.

Now, we have :-

Area of a square = Side × Side.

Side of this square = 10 cm.

So, area = 10 × 10 = 100 sq.cm.
