Question

The circular portions of the following figures are semicircle. For each of the following figures, find
a) its perimeter
b) its area

Answer 1

Answer:

parameter of the figure we must find out parameter of semi circle and parameter of of rectangle that is present inside is Semi circle

then at both parameters and we find out the whole perimeter of the figure

perimeter of 2 semicircle=2(πd/2)

=3.14*21

=66m

perimeter of rectangle=2(L+b)

=2*(21+15)

=72m

total parameter of the figure is 66+72

=138m
