Answer:
So I don't know the equation but I know the answer.
Length: 170 ft.
Width: 100 ft.
Explanation:
The perimeter (The length all around) is 270. You do the perimeter divided by two and add 35, because we know they are almost equal except for one side is 35 ft. longer, That is your length. You the take the perimeter minus the length to get the width.
Equationish: P÷2= x+35= y -> P-y=w
Or: 270÷2= 135+35=170 -> 270-170= 100ft.
