Question

find the area of the pool deck. (part with the umbrellas and chairs). area = length · width find the area of the pool. (just the swimming area) area = length · width

Explanation:

Step1: Calculate pool - deck area

The length of the pool - deck is 8.5 ft and the width is 18 ft. Using the formula $A = l\times w$, we have $A_{deck}=8.5\times18$.
$A_{deck}=153$ square feet.

Step2: Calculate pool area

The length of the pool is 11.5 ft and the width is 18 ft. Using the formula $A = l\times w$, we have $A_{pool}=11.5\times18$.
$A_{pool}=207$ square feet.

Answer:

The area of the pool - deck is 153 square feet. The area of the pool is 207 square feet.
