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

The area of the garden is  441 sq ft

A square is a quadrilateral with four equal sides.

Characteristics of a square includes:

• The diagonals bisect each other at 90°.

• Opposite sides parallel and of equal length

• The four angles of a square are equal.

Perimeter of a square =4 x length

84 = 4 x length

divide both sides of the equation by 4

84/4 = length

length = 21 feet

Area of a square = length²

21² =  441 sq ft

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
