Answer 2

Answer:

160 rupees

Step-by-step explanation:

Area of the lane / Area of the brick is the first part of the answer.

1.2 km = 1200m.

So,

4 x 1200 = 4800 = area of lane

20 x 12 = 240 =  area of each brick.

4800/240 = 20 = no of bricks required.

Cost of each brick = 8000/1000 = 8 rupees

Cost to make the pavement = 20 x 8 = 160 rupees
