Question

A rectangular field is80 m long .find perimeter and breadth of the plot if its leveling costs rupees6000at rupees

3 per m2

Answer 1

As given in the question total cost is 6000 at rate of 3 rs per m2

So area = 6000/3

Area = 2000 metre square

Now to find breadth

Area = length × breadth

2000 =80 × breadth

Breadth= 2000/80

Breadth = 25 metre

Perimeter = 2(length + breadth )

Perimeter = 2×(80+25)

Perimeter=2×105

Perimeter = 210 metre Answer
