perimeter of the rectangle =length of the wire
=2(l+b)
= 2(66)
circumference =length of the wire
2pi.r=2(66)
r=21
radius =21 cm
hope this helps u

According to given sum,
perimeter of rectangle = circumference of circle
let radius of the circle be r.
=2*(l+b)=2*pie*r
=l+b=pie*r
=35+31=22/7*r
=66=22/7*r
r=21
:-)hope it helps u.
