Find the perimeter and area. (plz with this problem)

The first step to solving this problem is to find the area and circumference of the half circle using these equations:
and
d= diameter
r= radius
C= circumference
a= answer

So the the "d" of the half circle is 10, and half of 10 is
. Because we are solving for only half of the circle this is what happens:


Now we just add the other sides together:
The Perimeter is 55.86

Now for the area we must use a similar equation for the half circle:


This is the area of the whole circle so we have to divide 78.54 by half to get our answer, which is 39.27

This is the area of the rectangle
Is the area of the whole shape

Perimeter= 55.86
Area= 229.27
