Question

38) A rectangular park 60 metres long and 40 metres wide has two roads, each 5 metres wide, running at right angles to each other in the middle of the park, one parallel to the length and the other parallel to the width. Calculate the cost of constructing the roads at Rs. 25.00 per square metre.​

Answer 1

Answer:

₹285

Step-by-step explanation:

Given,

A rectangular lawn 60 meters by 40 meters has two roads each 5 meters wide running in the middle of it one parallel to length and the other parallel to breadth

Area of the road=40×5+60×5−5×5

                          =200+300−25

                          =475sqm

Given,

Cost of graveling the roads =60 paise per sq meter.

∴475×60paise

=28500 paise

=Rs.285
