Answer:
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
