wide. How many feet of fencing does he need?
(1) 10
(2) 30
(3) 40
(4) 80
(5) 120

Answer 1

Answer:

(5) 120.

Explanation:

To calculate the amount of fencing needed to enclose a rectangular area, we need to find the perimeter of the rectangle. The perimeter is the sum of the lengths of all four sides.

In this case, we are told that the rectangular section of Pete's backyard measures 30 feet in length and is also 30 feet wide.

Therefore, the perimeter of the rectangle is:

P = 2L + 2W

where L is the length and
W is the width of the rectangle.

Substituting the given values, we get:

P = 2(30) + 2(30) = 60 + 60 = 120

Therefore, Pete needs 120 feet of fencing to enclose the rectangular section of his backyard.
