The area of a square is 441 square centimeters whose
side is half the radius of a circle The circumference of a circle is equal to the width of a rectangle If the perimeter of the rectangle is 712 cm What is the length of the rectangle?ÂSolution
Let side of square =x Then given- x²=441cm² X= 21cm X=r/2 r= 42cm according to qs- 2 πr = b b=2×22/7×42 b= 44×6=264cm perimeter of rectangle =712 2(a +b) =712 a +b=356 a=356-264=92cm.
