diagonal of the square will be the diameter of the circle:
for the square diagonal: 3.4 root under 2
circle area = pi 3.4 * 3.4 *2
for the rectangle: root under (3.2 ^ 2 + 25)
circle area = pi 3.2^2 + 25
we can ignore the pi as this is the constant
comparing the other numbers, square of 34 will be greater as multiplied by 2 times further,
ans A
