Question

Find the perimeter of the given shape (Take π = `22/7`).

Answer 1

The outer boundary, of this figure, is made up of semicircles.
Diameter of each semicircle is 14 cm.

We know that:
Circumference of the circle = πd
Circumference of the semicircle = `1/2`πd

= `1/2 xx 22/7` × 14 cm

= 22 cm

Circumference of each of the semicircles is 22 cm

Therefore, perimeter of the given figure = 4 × 22 cm = 88 cm.
