Answer 2

Answer:

50km^2

Step-by-step explanation:

hey mate here is your answer:

given,

length of road=40km

breadth of road=250m

$1km = 1000m$

.:length of road=40km=40×1000m=40000m

to find:

cost of tarring of road

solution:

as they given the cost in the units of km^2,that indicates we need to find first area and then next cost.

$area \: of \: rectangle = length \times bredth$

.:area of rectangle=40000m×250m

area of rectangle=10000000m^2

$1m = 1 \div 1000km$

$1m ^{2} = 1 \div 1000000km {}^{2}$

area of rectangle=10km^2

.: cost of tarring per km square=Rs5

.:for 10km^2= 10×5=50km^2
