Question

the total cost of leveling the ground at ₹3per sq. is ₹4725.Find the area of the ground

Answer 1

cost of leveling ground = Rs. 3 per (m/cm) sq.  

let the area be ' a '

ACCORDING TO THE QUESTION  

cost of leveling ground of a ( m/cm) sq. at Rs.3 = Rs.4725

=> a X 3 = 4725

=> a = 4725/3

=> a = 1575

so the area = 1575 (m/cm)sq.

CHECK  

1575 X 3 = 4725

I have written (m/cm) because you haven't mentioned it. (m or cm?)
