The Smiths have a pool that is 20 feet by 35 feet.

A 5 foot wide deck completely surrounds the pool.

The average depth of the pool = 6 feet.

How much surface area is covered by the proposed pool deck?

Thats not right

I'll be glad to check your answer.

A=LxW

20ft.x35ft=700 ft
I added 5 ft to both to include the deck
25ftx40ft= 1000
I subtract the area of pool from above amount
1000-700= 300 ft.
Is that correct?

Right!

wow. :-)

You're doing great!!
