Answer 2

Hi !!!

Here is your answer,

Given : -
Cost of ploughing at rate of Rs.10 is Rs.123210

Let the area of the square field be 'x' m sq.
So,
➡x*10 = 123210
➡x = 123210/10
➡x = 12321

Area of square field = x = 12321 m sq.

Area = (side)^2
➡12321 = side*side
➡√12321 = side
➡111 = side

Each side of square field = 111 m

Perimeter of square field = 4*side
= 4*111
= 444 m

If the cost of fencing the square field per 1 m = Rs.7
Than,
the cost of fencing the square field of perimeter 444 m = 444*7 = Rs.3108


Hope it helps.
