Answer:
Step-by-step explanation:
Given that a rectangle is inscribed in a circle of radius r.
Since diameter subtends right angle at the circumference we get diagonal of the rectangle is diameter of the circle
Let l and w be the dimensions
Then
Hence A =lw maximum when A square is maximum
i.e.
Use derivative test
I derivative =
II derivative <0 for non zero value of l
Hence maximum when
Or rectangle is a square with equal sides
