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.
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.
