Question

find the perimeter of the given figure above​

Answer 1

Answer:

100cm

Step-by-step explanation:

parimeter = 2×pi×r + 2×28

= 2× (22/7)×7 +56

= 44+56 = 100 cm

Answer 2

Answer:

100

Step-by-step explanation:

perimeter of one semicircle is 22/7 * 7 = 22

perimeter of two semicircles is 44.

length of rectangle is 28 and it breadth is 14 ( diameter of semicircle).

perimeter of rectangle is 2(l+b).

= 2( 28+14)

= 2( 42)

= 84

perimeter of figure = perimeter of semicircles + perimeter of rectangle - diameter of semicircles

= 44+84-28

=128-28

= 100
