बेरीज
उत्तर
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.
