Question 88048
Let the width of the field be x

Length = 2x -5

Perimeter  = x + x + 2x - 5 + 2x - 5 = 6x - 10

Given that perimeter = 230 ft.

so, 4x - 10 = 230

Add 10 on both sides

6x = 230 + 10
6x = 240

Divide both sides by 6, you will get

x = 240/6 = 40

length = 2x - 5 = 2*40 - 5 = 80 - 5 = 75

Answer: length = 75ft. & width = 40ft.
