Area of rectangle = 36 x 20 = 720 ft^2

Perimeter of rectangle = 2(36 + 20) = 112 ft

Area of semi-circle = 1/2πr^2 (r = 18/2 = 9, using π = 3.14<span>)
= 1/2 x 3.14 x 9^2
= 142.87 ft^2

</span>Perimeter of semi-circle = πd = 3.14 x 18 = 56.52 ft

<span>(a) What is the total area of the swimming pool? Explain your reasoning.
</span>
area of the swimming pool = area of rectangle - area of semi-circle
area of the swimming pool = 720 ft^2 - 142.87 ft^2 = 577.13 ft^2

answer:
area of the swimming pool = 577.13 ft^2

--------------------------------------------------------------------------
<span>(b) What is the perimeter of the swimming pool? Explain your reasoning.
