If x= the width of the rectangle, then the length = 2x + 3. Since the perimeter is 72 inches, and we know that a rectangle has two sides equal to the width and 2 sides equal to the length, we would construct the following equation:
2x + 2(2x +3) = 72
2x + 4x + 6 = 72
6x = 66
x = 11
Since the width of the rectangle (x) is 11 inches, the corresponding length would be 2x + 3 = 2(11) + 3 = 25. Therefore, the length of the rectangle is 25 inches.
