The length of a rectangle is twice the diameter circle.The circumference of the circle is equal to area of a square of side 22cm.What is the breadth of rectangle if its perimeter is 668cm?
Side of square=22cm
Area=22*22=484
Circumference=2 π*r=484=2*22/7*r=484
R=77 diameter=154 ,length of rectangle=2*154=308
Perimeter=668 ,2*breadth=668-(2*308)=668-616=52 ,breadth=26
