Solution
The side of square field = 100 m
Area of square field = (side)2
= (100)2 m2
= 10000 m2
The cost of levelling an area of 1 m2 = Rs 5
So, the cost of levelling an area of 10000 m2 = Rs 5 × 10000 = Rs 50,000
Area of square field = (side)2
= (100)2 m2
= 10000 m2
The cost of levelling an area of 1 m2 = Rs 5
So, the cost of levelling an area of 10000 m2 = Rs 5 × 10000 = Rs 50,000
