Answer:
the length of the park is 70m its width is 60m. The roads should have the same length so their area is 70m x 8m, =560m^2.
the cost of leveling the roads per m^2:
we have two roads so their total area is 560 x 2 = 1120m^2
now multiply this by Rs.15 to get the cost of leveling everything.
this is 1120 x 15
this gives Rs.16,800
