Math Problem

Here is the problem from today.  Just in case you need it to finish your homework.

Mr. Humphrey is trying to build the garden that the eco-team planned for the school. He knows the area of the garden is 50m2 and that one side of the garden should be 25m. How long should he cut the wood for the other side of the garden? How much wood does he need in total?
