Question

1 Find the area of a square whose perimeter is 9 m. 11​

Answer 1

Resposta:

Hi

A square has four sides of the same length.

Let "x" be the length of one side of the square.

The perimeter (P) is:

P = 4 . x

P = 9 m, so:

4 . x = 9

x = 9/4

x = 2,25 m

The area (A) is:

A = x²

So:

A = 2,25²

A = 4,5 m²
