Correct Answer - Option 1 : 16 meter
Given:
The total cost of ploughing = Rs. 2048
Per meter square cost of ploughing = Rs. 8
Formula Used:
Area of square = Side × Side
Total cost = Area of field × Per meter square cost
Calculation:
The total cost of ploughing = Area of field × Per meter square cost of ploughing
⇒ 2048 = Area of field × 8
⇒ 2048/8 = Area of field
⇒ 256 m2 = Area of field
Area of field = Area of Square
Area of square = (Side)2
⇒ 256 = (Side)2
⇒ √256 = side
⇒ 16 m = side
∴ The side of the square is 16 m.
