Pernimeter of the rectangle = 2(l+b)
=2(17+5)

=44m
Perimeter of semi circle =Pie*r
=3.14*17
=53.38m

Answer:

radius of both circle = 16/2=8cm

perimeter of figure something= circumference of. 2 semi-circle + 2 breadth of the rectangle

=2*1/2* 2πr

=2πr + 6 cm

=2*3.14*8 cm

=50.24+6cm

= 56.24 cm
