explain it
please
what you give that's the area not perimeter
perimeter is π35 cm
wait. what.
no

without'22/7'
because C is the center so AC=CB. BOTH SEMICIRCLE with same radius..

perimeter of full shape =perimeter of semicircle AtoC + semicircle CEB+semicircle AtoB
AC=AB/2.
C is mid point
perimeter of AtoC=πr=πAC/2 = πAB/4
Similarly
perimeter of CEB= πAB/4
perimeter of AtoB = πR = πAB/2
now
total perimeter= πAB/4+πAB/4+πAB/2=πAB
=
AC=AB/2.
