Paolo is putting a fence around his pool. The length of the pool is 20 feet, the width is (20 minus x) feet, and the area of the pool is 300 square feet. Recall that area is length multiplied by width. The equation below models the area of the pool. 20 (20 minus x) = 300

Answer :

Answer:

(A) x=5

Step-by-step explanation:

  • The length of the pool is 20 feet,
  • The width is (20 minus x) feet; and
  • The area of the pool is 300 square feet.

Area = Length X Width

300 =20(20-x)

Opening the bracket on the right hand side

300 =400-20x

20x=400-300

20x=100

Divide both sides by 20

x=5

The value of x=5
