You add the area of the rectangle to the area of a circle
OpenStudy (littlebird):
because you have a rectangle...and the two half circles onthe ends together make a circle
Rectangle area = length x width
Circle area = pi x radius^2
The length is 20
The width 4
The radius is half the width

So radius is 2
OpenStudy (littlebird):
Rectangle area = 20 x 4 = 80
Circle area = pi x (2)^2 = 4pi = 12.56
OpenStudy (littlebird):
Then you add them
OpenStudy (littlebird):
You get 92.56
OpenStudy (littlebird):
Which you round up to get 93
