Answer:

a) 64.37m^2 b) 15.71 meters

Explanation:

Area of circle =
\pi r^2

Rectangle: quadrilateral, parallelogram, all angles are 90 degrees

a) The area of the park not covered by the wading pool is equivalent to the area of the wading pool subtracted from the total area:

because the radius of the pool is 2.5

Area of wading pool =
\pi 2.5^2=6.25\pi m^2

The total area of the park is length x width because it is a rectangle

Area of park =
14*6=84m^2

Area of the park not covered by the wading pool =
84-6.25\pi ≈ 64.37m^2

b) The meters of fence needed to surround the circular pool is the circumference of the circle

Circumference:
2.5*2\pi=5\pi
15.71
