The Dehejias are

remodeling their house

and changing the

landscaping of their yard.

The drawing at the right is a

diagram of the deck at the

back of their house. In order

to put more trees in their yard, the Dehejias

plan to cut the shaded areas off the deck. What

will the new area of the Dehejias’ deck be?

In This Chapter You Will:
