Answer:

Surface Area: 278.5 m

Way Around:  81.4 m

Step-by-step explanation:

        So we can find the radius of the circle by taking 15 from 20, which results in 5.

The surface area of the pool will be the area of the rectangle + the area of the circle:

20 * 10 = 200

~~~

A = πr²

A = π(5)²

A = 78.5

200 + 78.5 is 278.5 m

Now, for the perimeter:

20 + 10 + 15 + 5 = 50 m

~~~

C = 2πr

C = 2π(5)

C = 31.4

50 + 31.4 = 81.4 m

        I hope this helps! They may be looking for your to subtract the overlap, but as I am not sure if they are I left that out. Good luck and have a great day! :D
