Question

Mr.voss has 100 feet of fencing to build a rectangular play pen for his new chickens.The width of the play pen is 15 feet, What are the possible lengths of the play pen ?

Answer 1

Two widths consume 30 linear feet of fencing material.

That leaves 70 ft of fencing to make two lengths.

So the lengths can be any positive number not exceeding 35 ft.
