If the perimeter of a square is 18 M find its side and its area with explanation

The side of the square is 4.5 m. The area is 20.25 m.

Step-by-step explanation:

The perimter is the length + width + length + width. Since a square has equal lengths and widths it’d be 4 x length.

P = 4x

We know the perimeter of the square is 18 m.

18 = 4x

We want to try to isolate x so we divide 18 by 4.

18/4 = x

4.5 = x

Each side is 4.5 m.

—

The area is length times width.

A = l x w

We know the length and width is 4.5

A = 4.5 x 4.5

A = 20.25
