Question

find the perimeter of this figure

Answer 1

Firstly we will find circumference of semi circle which is equal to 22/7*14=44cm
Then we will find the perimeter of triangle which is equal to 14+21+21=56cm
Then add both of them and we will get
44+56=100cm

Answer 2

Step-by-step explanation:

Note: Since value of π is not given, I will take π= 22/7

circumference of the semi-circle

=πd/2

=22/7x14÷2

=22 cm

again, sum of the remaining sides=21+21=42 cm

therefore, perimeter of the figure= circumference of the semi-circle+sum of the remaining sides=22+42cm=64 cm
