Thread: Dimensions of Rectangular Garden

Mr. James wanted to plant a garden that would be in the shape of a rectangle. He was given 80 feet of fencing to enclose his garden. He wants the length to be 10 feet more than twice the width. What are the dimensions, in feet, for a rectangular garden that will use exactly 80 feet of fencing?

Please, set up the equation and I will solve for x.

ok perimeter is



and length is



so now substitute L into the perimeter formula



and solve

I can surely take it from here.
