Question
What is the difference between (in m2) the
area of a circular field of radius 14 metres and area of a rectangular piece of land having its dimensions as 20 metres Ă— 10 metres?Solution
Area of the circular field = π × radius2 = (22/7) × 14 × 14 = 616 m2 Area of the rectangular piece of land = length × breadth = 20 × 10 = 200 m2 So, difference in area = 616 – 200 = 416 m2
