Question

Find the perimeter of the square whose area is 225m².
​

Answer 1

Step-by-step explanation:

area = 225m square

= side square = 225 m square

therefore, side =

$\sqrt{225}$

= 15

now, perimeter = 4 × side

= 4 × 15

= 60

therefore, perimeter of the square = 60 metres

Answer 2

Step-by-step explanation:

Perimeter of square = 4×side

4a( "a" is the side of a square )

Area of square = a×a

Firstly we have to find side..

If area of square = 225m² then side (a) = ?

a² = 225m²

a = _/`225 m² (Root of 225 m²)

a = 15m

Then find perimeter of the square

Perimeter of square = 4a

a = 15

4a = 15 × 4

4a = 60

Hence , the perimeter of square = 60
