Answer 2

Given data :

• Length of the road = 10 km
• Breadth of the road = 3 m
• Cost of paving road = Rs 4.50 per m².

To find : Cost of paving road ?

Solution : Firstly we have to convert length of road in metre.

⟹ Length of the road = 10 km

⟹ Length of the road = = (10 * 1000) m

⟹ Length of the road = 10000 m

Now, to find area of the road,

⟹ Area of the road = Length * Breadth

⟹ Area of the road = 10000 * 3

⟹ Area of the road = 30000 m²

Now,

⟹ Cost of paving the road

= Area of the road * cost of paving

⟹ Cost of paving the road

= 30000 * 4.50

⟹ Cost of paving the road

= Rs 135000.

Answer : The cost of paving a road is Rs 135000.
