Question

one side of a square field is 300 M find its area find the total cost of levelling this field is if the cost of levelling the field is Rs 0.50 per square metre

Answer 1

Length= 300m, so in square all sodes are equal.
Area of square=lengthxlength
I.e., 300x300=90,000m.
Now,
Cost of levelling 1 sq meter=rs 0.50
So total cost = 90,000x0.50
= rs 45,000

Answer 2

Answer:

Area of square field = 90000 and Cost of levelling = Rs 45000

Step-by-step explanation:

Side = 300m

So, Area of square = (Side)²

= (300m)²

= 90000m²

Now,

Cost of levelling 1m²=Rs 0.50

So, Cost of levelling 90000m²=Rs 0.50 * 90000

=Rs 45000
