Question

Find the length of the rectangular field whose breadth is 45 m if the cost of levelling the field at the rate of 2 rupees per square metre is 8100 rupees

Answer 1

Hey friend

Cost of levelling= rate of levelling × area of
rectangular field

8100=2×area of rectangular field

area of rectangular field=4500m^2

Now,
Area of rectangular field=Length×Breadth
4500m^2=length×45m
Length =100m
