Question

Fin the cost of leveling a ground at the rate of Rs. 12 per sq m if it is 45m long and 30m wide

Answer 1

length=45m
breath=30m
area=l*b
45*30
=1350 m sq
cost at 1m per sq= Rs.12
cost at 1350 m sq= Rs.12*1350
=Rs. 16200

Answer 2

Length of the ground = 45m
Breadth of the ground = 30m
Therefore,area of the ground is (45×30) m^2
=1350m^2
Cost of levelling 1m^2 of the ground is Rs12
Therefore, cost of levelling the whole ground is Rs (1350×12) = Rs 16200
