There is a rectangle that is 4 inches wide. If the rectangle's perimeter is 30 inches, what is the area of the rectangle?
Let's be accurate as possible and think first.
44
Twice the height of the rectangle is 30 inches - 2 * 4 inches = 22 inches.

The rectangle's height is 22 inches / 2 = 11 inches.

The area of the rectangle is 4 inches * 11 inches = 44 square inches.

.

Therefore, the answer is 44
