​

Answer 1

Dear student,

By using measuring tape,measure the diameter of the circular field ie from one side of the circular field to the other side.Now divide the diameter by 2 which gives radius of circular field.Now using the formula $A=\pi \times r^2$ we can find area of circular field.Where value of π is 3.14 and r is the radius of the circular field.

Regards.
