Length of a side of a square field is 275 m. What will be cost of levelling the field at a rate of 10 cent per square metre?
$ 7564.2
$ 7568.50
$ 7542.62
$ 7562.50
Explanation:
Length of the square field = 275 m
Area of the square field = side × side
= 275 m × 275 m
= 75625 m2
Cost of levelling the field for 1 sq m = 10 cent.
Now, we have to find the cost for entire area ie 75625 sq m.
Cost of levelling the field = 75625 × 10 cent
= 756250 cent
= $ 7562.50
