heyy frnd...
here is Ur answer
perimeter of rectangle=circumference of circle
perimeter of rectangle=2(l+b)
=2(18.7+14.3)
=2×33
=66cm
circumference of circle=66m
2πr=66m
2×22/7×r=66m
44/7×r=66m
r=66/1×7/44
r=1.5×7
r=10.5cm
hope this helps u....

area of the rectangle=L×B
area=267.41 sq.cm
Area of the rectangle=Area of the Circle
Area Of the circle=π×r×r
Area of the circle=267.41 sq.cm
267.41=22/7×r×r
r=267.41×7/22
r=85.085 sq.cm
area=267.41 sq.cm
