Answer:

69,000

Step-by-step explanation:

Area of the road parallel to the length= 70mx5m= 350m^2

Area of the road parallel to the breadth= 50mx5m3250m^2

Area of the portion of the road overlapping=D 5mx5m325m^2

Total area of the road= (350m^2 + 250m^2)- 25m^2 = 575m^2

Cost of construction= 120x575%3D Rs. 69,000
