Hi Anushka


2216_10490_Circle problem.JPG


Here in  h = r sin θ , 


The area of a rectangle ie. length * breadth or


{BD X (AO +CO)}  ie {2r X (h+h)}


by dividing rectangle in two half triangles and calculating each. (half X base X Height) X 2


will be maximum when h will be max. and h is maximum only when θ = 90.


which makes rectangle a square
