Question 65979
Let the width of the field be x ft.
So length = (2x-5) ft

Perimeter = 2[ length + width]
==> 2[2x-5+x] = 230
==> 2{3x-5} = 230
==> 6x - 10 = 230
==> 6x - 10 + 10 = 230 + 10
==> 6x = 240
==> 6x/6 = 240/6
==> x = 40

Thus the width of the field = 40 ft.
Length = 2x-5
       = 2*40 - 5
       = 80 - 5
       = 75 
Width = 40 ft and length = 75 ft


Good Luck!!!
