Expert Solution
Step 1

One side of the parallelogram measures 32.

Height of the parallelogram is 11.

Then the area of the parallelogram is:

=32×11=352

The other side of the parallelogram becomes the diameter of the semicircles.

The diameter of the semicircle measures 16.

So the radius of each semicircle is = 16/2 = 8

Therefore the areas of both the semicircles is:

=2×12×π82=64π
