D. 50

Answer 1

The perimeter of the given figure is 25 units .

Option (C) is correct .

Explanation:

Formula

`Perimeter\ of\ semicircle = \pi\ r`

Where r is the radius of the circle .

As given

Radius of semi-circle = 2 units

`\pi = 3.14`

As perimeter is the sum of the boundary length .

Thus

Perimeter of the figure = Perimeter of four semi- circle .

= 4 × 3.14 × 2

= 25.12

= 25 units (Approx)

Therefore the perimeter of the given figure is 25 units .

Option (C) is correct .
