Question

arun is a farmer. he erected a fence around his paddy in square shape field. he used 20 poles in each side at a distance of 4m .what is the area of the field ?​

Answer 1

Given,

Number of poles = 20

Distance between two poles = 4m

To find,

The area of the field.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First of all, we have to calculate the number of poles in each side.

Number of poles in one side of the square field

= (Total number of poles ÷ Total sides of square field) + 1

= (20÷4)+1

= 5+1

= 6

Now, the number of gaps between 6 poles

= (Total number of poles - 1)

= (6-1)

= 5

Total length of one side

= ( Number of gaps × distance between two poles)

= (5×4)

= 20m

Area = (side)² = (20)² = 400 m²

Hence, the area of the field is 400 m².
