Answer 1

Answer:

Rs. 273000

Step-by-step explanation:

area of field=1/2*base*height

=1/2*420*325

=1/2*136500

=68250

cost= Rs.4*68250=Rs. 273000

Answer 2

The cost of levelling the field is  ₹ 273000

Explanation:

Given : Base of a triangular field = 420m

Altitude = 325m.

Formula : Area of triangle = (0.5) (Base)(Altitude)

So , Area of field = (0.5) (420) (325) =68250 sq. m

Rate of levelling = ₹4 per square metre

Then, the cost of levelling the field = (Rate of levelling) x (Area of field)

4 x(68250 ) =  ₹ 273000

Hence, the cost of levelling the field is ₹ 273000.
