Question

Lucy’s parents built a swimming pool in the backyard. Use 3.14 for π.

What is the distance around the pool? The distance around the pool is
131.4/ 162.8/ 957/ 1114 feet.



What is the area of the pool? The area is 131.4/ 162.8/ 957/ 1114 square feet.

Answer 1

Distance around the pool = 162.8 feet

Area of the pool = 957 square feet

Explanation:

Distance around the swimming pool = Perimeter of the pool

Perimeter of the pool which is a composite figure will be,

= Circumference of the semicircle + Sum of three sides of the pool

= πr + 2×(length of the pool) + width of the pool

= 3.14×(10) + 2×40 + 20

= 62.8 + 80 + 20

= 162.8 ft

Area of the pool = Area of the semicircle + Area of the rectangular pool

=
`(1)/(2)(\pi)(r)^(2)+(\text{length}* \text{Width})`

=
`(1)/(2)(3.14)(10)^2+(40* 20)`

= 157 + 800

= 957 square feet
