Answer 1

plz tell me if ans is right

Answer 2

Answer: 47.6 cm

Step-by-step explanation:

See, there are two semicircles and one rectangle ,if you have observed the figure well.

Okay, coming to the point the perimeter of the figure will include circumference of the small semicircle ,bigger one the breadth of the rectangle, and 4 cm.

Let the radius of small semicircle be r' and of larger one be r.

Then,

Perimeter = 4 +2πr +2πr' + 3 + 3

= 4 +3.14*2*4 +2*3.14*2 + 6

= 10 + 3.14*2(4+2)

= 10+ 6.28(6)

= 10 + 37.68

= 47.68

The perimeter of the given figure is 47.6 cm.
