Question

A field is 225 m long and 175 m wide. It
has two roads in its centre of uniform width
of 5 m, one parallel to its length and the
other parallel to its breadth. Find the cost of
levelling the roads at 3 per square metre​

Answer 1

Answer:

We see that the total road to be levelled= horizontal road+vertical road-the common portion to both.

Area of horizontal road= 225m×5m=1125m

2

Area of vertical road=175m×5m=875m

2

Area of common portion: 5m×5m=25m

2

Thus total area:(1125+875−25)m

2

=1975m

2

Rate: Rs.3 per m

2

So, total cost=1975m

2

×Rs.3 per m

2

=Rs.5925
