If the perimeter of a square garden is 84 feet, what is the area of the garden?

А 21 sq ft

B 84 sq ft

С 336 sq ft

D 441 sq ft

D

Step-by-step explanation:

A square has 4 equal sides, so than divide 84 by 4 sides and you get 21.

Area of a square is A^2, so just take 21^2 = 441

D. 441

Step-by-step explanation:

All sides of a square are equal. Due to this, the perimeter can be expressed as 4 times the side of the square. Let x be the side of a square.

Then we have:

4x = 84

x = 21

The area of a square is written as x^2, as x is both the length and the width.

So your answer will be:

(21) ^2 = 441
