Answer:
768ft^2
Step-by-step explanation:
Kindly see attached file for a rough sketch of the pool and the deck for your reference.
from the sketch
the lenght of pool and deck combined is = 52ft
and the width of the pool and deckcombined is = 24ft
now the area of the pool and the deck combined is =52*24
= 1248ft^2
The area of the pool is = 40*12
=480ft^2
Therefore the area of the deck is= area of combined pool and deck- area of pool
= 1248-480
=768ft^2
