Question

If a rectangle has a perimeter of 36 feet and is 4 feet wide, what’s the area? How do you solveOr what’s the formula

Answer 1

Answer:

The area of the rectangle is 56 square feet

Step-by-step explanation:

Given that the perimeter of a rectangle is 36 ft.

Since it is 4 ft wide, let the length be x.

Then

2(4 + x) = 36 (Perimeter of a rectangle is 2(l + w))

8 + 2x = 36

2x = 36 - 8

2x = 28

x = 28/2 = 14

The area of a rectangle

A = l * x

= 4 * 14

= 56 square feet.
