Question

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

semicircle. Rounded to the nearest tenths place

Answer 1

38.6 units.

Explanation:

The given figure is composed of a parallelogram and one semicircle.

We need to find the perimeter of the parallelogram.

Perimeter = sum of all sides

ATQ,

P = 9+8+9+(2πr/2)

i.e.

`P=26+\pi r\\\\=26+3.14* 4\\\\=38.56\ \text{unit}`

or

= 38.6 units

So, the perimeter of the figure is equal to 38.6 units.
