The road roller is cylinder
Radius=84/2=42cm
Length=1m=100cm
Lateral surface area=2rh
=2*22/7*42*100
=26400cm^2
Area levelled by roller in one revolution=26400cm^2
Area levelled by 750 revolutions=750*26400cm^2
=750*26400
----------------m^2
100*100
=15*132m^2
=1980m^2
therefore,area of road levelled by roller =1980m^2
