Answer 2

Answer:

Hello dear

I have attached

perimeter of semi circle ADC= 22/7*r

Radius of semi circle ADC= AC/2

AC=2.8 + 1.4c

AC/2=4.2/

Perimeter of ADC= 22 /7*2.1

= 6.6cm

Perimeter of semi circle BFC= 22/7*1.4/2.

= 22/7*0.7

=2.2cm

Perimeter of semi circle AEB= 22/7*2.8/2

=22/7*1.4

=4.4cm

Perimeter of shaded region = Perimeter of semi circle ADC - Perimeter of semi circle AEB + perimeter of semi circle BFC..

Perimeter of Shaded region = (6.6-4.4+2.2)cm

=4.4cm

The Perimeter of shaded region is 4.4cm
