@israa88 could you help me with this last one too? This is the last question I don't understand

anonymous · Answer

so 650 sq ft would be the overall of the whole pool?

anonymous · 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.
