Dharmesh has a square garden with a perimeter of 132 feet. Is the area of the garden greater than 1,000 square feet?
Delvig [45]

Answer: Yes. The area is 1089 square feet.

Step-by-step explanation:

For a square, all the sides are equal: L = W

Hence, the perimeter of a square = 4 × L

Perimeter = 4L

132 = 4L

132 ÷ 4 = L

33 = L = W

Area of a square with 33 feet sides = L × L = 33 × 33 = 1089

1089 > 1000

Maurinko [17]
"Around the garden"= circumference

Find diameter from circumference formula

Circumference= πd
19= (3.14)d
divide both sides by 3.14
6.04788= d

Find radius
d÷2= 3.0239

Insert r= 3.0239 into Area formula

Area= πr^2
A= π(3.0239)^2
A= (3.14)(3.0239)^2
A= 28.71 square feet

ANSWER: 28.71 square feet is the area of the new garden

Hope this helps! :)
