Question

Which of the following has larger area and by how much?
a. Rectangle with length 10 cm and breadth 6.28 m

b.Circle with diameter 4.2 m​

Answer 1

Answer:

area of rectangle= length x breadth

= 10 x 6.28

= 62.8 cm sq

area of circle = πrsq

22/7 x 2.1 x 2.1 ( as 4.2 is diameter)

= 13.86 cm sq

Hence area of rectangle is more

by (62.8-13.86) 48.96 cm sq
