As the same wire is used perimeter of rectangle=perimeter of circle
perimeter of rectangle=2(l+b)=2(57+35)=2×92=184
perimeter of circle=184
so 2 \pi r=184
 \frac{22}{7}  ×r=184

so r= \frac{184*7}{2*22}

so r= \frac{322}{11} cm

area= \pi

= \frac{22}{7}* \frac{322}{11} *\frac{322}{11}

= \frac{29624}{11} cm²
