A rectangle of length ‘x’ and breadth ‘y’ is inscribed in a semi-circle of fixed radius ‘r’ as shown in the figure given below. Based on the above information answer the following question: |
Maximum area of the Rectangle is: |
2r2 3r2 r2 4r2 |
r2 |
Area to be maximum ⇒ r2 sin 2θ is maximum Maximum value of sin2θ = 1 . Maximum Area = r2 |
