Question

a deck surrounds a rectangular swimming pool. what is the area of the pool and deck? 4.ns0.2.3

Explanation:

Step1: Find the length of the outer - rectangle

The length of the pool is 24 yards and there are 2 - yard wide decks on both sides. So the length of the outer - rectangle $l = 24+2 + 2=28$ yards.

Step2: Find the width of the outer - rectangle

The width of the pool is 5 yards and there are 2 - yard wide decks on both sides. So the width of the outer - rectangle $w = 5+2 + 2=9$ yards.

Step3: Calculate the area of the outer - rectangle

The area of a rectangle is given by the formula $A=l\times w$. Substitute $l = 28$ yards and $w = 9$ yards into the formula. So $A=28\times9 = 252$ square yards.

Answer:

252 square yards
