Answer:
₹3120
Step-by-step explanation:
The area of each sidewalk is it's width multiplied by its alternate side
So, total area of sidewalks
= first sidewalk+second sidewalk- area where these sidewalks meet
=
(150*10)m²+(120*10)m²-(10*10)m²
=1500m²+1200m²-100m²
= 2700m²-100m²
= 2600m²
Therefore cost=
₹(2600*1.20)
=₹3120.0
