    Circumference of a circle = $$2pi r$$ = 39.6 cm 2*(22/7)r = 39.6
    44/7 r = 39.6
    r = 6.3
    Area of circle = $$pi r^2$$ = (22/7)(6.3)(6.3) = 124.74 Let the length of the rectangle be l
    Since area of the rectangle is equal to area of circle​
    lb = 124.74
    l*4.5 = 124.74
    l = 27.72
