there is a circular field of area of approximately 500 square metre .How can you find its area accurately by using a measuring tape​?
​

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.
