Question

find the perimeter of each of the following shape take pi equal to 3.14
Answer - 132.80​

Answer 1

Perimeter of figure= 132.80 given

Length= 40m

Breadth= 15m

Diameter= 40m

To find radius= diameter/2= 40/2= 20m

To find perimeter of figure

Perimeter of rectangle= 110m by using formulae 2×(l+b)

Now,

Perimeter of semicircle

pie r+2 r

3.14×20+2×20

102.8m

Perimeter of figure

= Perimeter of rectangle+Perimeter of semicircle-80

= Perimeter of figure= 132.8m
