Answer 1

Answer:

A rectangular lawn 6060 meters by 4040 meters has two roads each 55 meters wide running in the middle of it one parallel to length and the other parallel to breadth

Area of the road=40\times 5+60\times 5-5\times 5=40×5+60×5−5×5

=200+300-25=200+300−25

=475 sq m=475sqm

Given,

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

\therefore 475\times 60∴475×60paise
