Question

find the perimeter of adjoining figure where AED is a semi circle and ABCD is rectangle

Answer 1

perimeter of rectangle-Perimeter of semi circle
2×34-7×36/7
68-36
32 is answer
I got 36/7 if you solve semicircle you got 36/7 ×r

Answer 2

perimeter=sum of all sides.

from fig. we get that the radius of the semicircle is 14/2=7 cm.

perimeter=20+14+20+pi*7

                =54+(22/7)*7

                =54+22

                =76 cm

Hope this helps
