The o'brien's are building a rectangular deck around the outside of their circular pool. a.) find the combined area of the deck and the pool if the deck is (2x + 3) units wide by (5x + 6) units long. (a =lw) show all work. b.)if the area of the pool is 3x^2 + 7x + 6, what is the area of just the deck?

A:

Width of the deck = units

Length of the deck = units

So area of rectangular deck = Length * width

=

Area =

Area= units square

As mentioned in part B, the area of the pool is so the combined area of the deck and pool is

Area = area of rectangular deck + area of pool

= unit square

B:

The area of only the deck is unit square
