Question

Find the Perimeter of the figure below, composed of a parallelogram and two

semicircles. Round to the nearest tenths place.
15
12

Answer 1

The Perimeter is 67.68 units

The circumference of the two semicircles is

• 2πr

Hence, we have ;

2 × π × (12/2)

=37.68 units

The Perimeter of the parallelogram in the figure:

• 15 + 15 = 30 units

Taking the sum ;

30 units + 37.68 units

= 67.68 units
