Question

19. It costs 38704 to fence a square field at the rate of 3 8.50 per metre. Find the area of the field​

Answer 1

Answer:

Area of the field  = 63164.26 $m^{2}$

Step-by-step explanation:

Total cost to fence a square field = 38,704 rupees

Rate to fence the square field = 38.50/m

Therefore, perimeter of the square field = 38704/38.50 = 1005.30 m

Perimeter of square = 4 $\times$ side of the square

⇒ Side of the square = Perimeter / 4

                                   = 1005.30 /4 = 251.325 m

Then Area of the field = side $\times$ side = 251.325 $\times$ 251.325 = 63164.26 $m^{2}$
