The length of a rectangle field is 7 m less than 4 times the width. The perimeter is 136 m. Find the width and length of the rectangle.

Let width be x m

perimeter = 2L + 2W

W = x and L = 4W - 7 = 4x - 7

so we have the equation

2 (4x - 7) + 2x = 136

8x - 14 + 2x = 136

10x = 150

x = 15

So the width = 15m and the length = 4 (15) - 7 = 53 m. Answer
