Question

find the perimeter of these figure.

Answer 1

Let’s take out for the square part first
Perimeter = 35* 3 = 105

Now for the semi circle
Circumference = 1/2 * 2* pi* r
R will be half of diameter i.e 35
Radius = 35/2

C = 1/2 * 2 * 22/7 * 35/2
C = 55

Total perimeter is 105 + 55 is —160

Hope it helps
