Answer:
c. 384 square feet
Explanation:
First, you must find the total area of the pool and deck combined. Because the deck is 4 feet wide and it wraps around the entire pool, 8 feet can be added to both the length and the width of the pool to get the measurements of the whole rectangle combined.
25+8=33
15+8=23
To get the total area you multiply 33 by 23
33 x 23= 759
Then you get the area of the pool alone by multiplying 15 by 25
15 x 25= 375
Then you subtract the area of the pool from the total area to get the area of the deck
759-375=384
