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 × 15 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 × 15 = 300 m2 So, difference in area = 616 – 300 = 316 m2
