Question

The length of a rectangle is 4 inches more than its width, and its perimeter is 36 inches. Find the width of the rectangle.

A.) 6 in.
B.) 11 in.
C.) 7 in.

Answer 1

B. 11 inches.

Explanation:

Answer 2

Let w be the width of the rectangle. From the given condition above, its length is therefore equal to w + 4. The perimeter (P) of the rectangle is twice the sum of its width and length. With the given,
36 in = 2 x (w + w + 4)
The value of w is 7. The length is therefore 11 inches.
