Question

Area of a square is 225 cm then what is its perimeter

Answer 1

✬ Perimeter = 60 cm ✬

Step-by-step explanation:

Given:

• Area of a square is 225 cm².

To Find:

• What is the perimeter of the square?

Solution: Let the meaure of side of square be s cm.

As we know that

★ Area of Square = (Side)² ★

A/q

• Area = 225 cm²

$\implies{\rm }$ 225 = (Side)²

$\implies{\rm }$ √225 = Side

$\implies{\rm }$ √15 $\times$ 15 = Side

$\implies{\rm }$ 15 cm = Side

So,the measure of each side of square is 15 cm.

Now,

★ Perimeter of Square = 4 $\times$ Side ★

$\implies{\rm }$ Perimeter = 4 $\times$ 15

$\implies{\rm }$ Perimeter = 60 cm

Hence, the perimeter of square is 60 cm.

Answer 2

Given that ,

The area of square is 225 cm²

We know that , the area of square is given by

$\large \sf \fbox{Area = { (Side)}^{2} }$

Thus ,

225 = (side)²

side = √225

side = 15 cm

Now , the perimeter of square is given by

$\large \sf \fbox{Perimeter \: of \: square = 4(Side)}$

Thus ,

Perimeter = 4 × 15

Perimeter = 60 cm

$\therefore \sf \underline{The \: perimeter \: of \: square \: is \: 60 \: cm}$
