Question

The length of a rectangle is 18 less than 4 times the width. The perimeter is 134 inches. Find the​ length, the width, and the area of the rectangle.

Answer 1

First, write an equation for the problem: 2(3w - 5) + 2w = 134 in. Simplify the equation and solve for w. 6w - 10 + 2w = 134. 8w = 144. w = 18. This means the width is 18. Plug this in for length. 3 (18) - 5 = 49. The length is 49.
