Question

A square has an area of 100 square meters. What is the perimeter of the square?

Answer 1

Hi,

Let the side of the square = a meters

Area of the square( A ) = a² m²

According to the problem given,

A = 100 m²

a² = 100 m²

a² = ( 10m )²

a = 10m

Perimeter of the square (P ) = 4a m

P = 4 × 10m

P = 40m

I hope this helps you.

:)

Answer 2

Hi !

Hi,

Side of the square = "a" metres

Area of the square = side x side =   a² metre square 

side x side = a²
A.T.Q,
a² = 100 m²

a = √100

a = 10 metres

==============================

Perimetre of a square = 4 × side
                                    = 4 × 10 = 40 metres
