Question

A rectangular garden is 185m long and 220m wide. It has two roads in its centre of uniform width of 4m, one parallel to its length and the other parallel to its breadth. Find the cost of levelling the roads RS.2.50 per square meter​

Answer 1

Answer:

Answer

Analyse the problem.

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
