A family needs to build fencing around their rectangular home and square swimming pool, depicted below. A rectangle labeled home has its right side labeled (2 + 5 x) yards and its bottom side labeled (3 + 10 x) yards. The square, labeled pool, is smaller than the rectangle. One of its sides is labeled (2x) yards.

The total amount of fencing they need can be written as _x + 10.
If x = 5
The family needs yards of fencing for their home.
