​

Answer 1

Answer:

Rs.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

Hope this answer will help you

Answer 2

Answer:

Step-by-step explanation:

Area of the longer road=2×50=100m^2

Area of the smaller Road =

2.5×40= 100 m^2

area of fields=50×40=2000m^2

area common to both the road

=2.5×2=5m^2

area of roads=200-5=195

=1805m^2
