Step-by-step explanation:
Length of roller = 1m = 100cm
Circumference of roller = π x D = 22/7 X 84 = 264 cm
Length of road = 264 x 750 = 198000 cm
Width of road = length of roller = 100 cm
Area of road = 198000 x 100 = 19,800,000 cm² or 1980

Step-by-step explanation:
Length of roller = 1m = 100cm
Circumference of roller = π x D = 22/7 X 77 = 224 cm
Length of road = 224 x 650 = 145600 cm
Width of road = length of roller = 100 cm
Area of road = 145600 x 100 = 14560000 cm² or 1456
