Step-by-step explanation:

Total length of the road = 4 km 800 m = 4 km + 800 m = 4000 m + 800 m = 4800 m (1 km = 1000 m)

Distance between two plants = 9.6 m

∴ Number of trees planted on each side of the road = (Total length of the road ÷ Distance between two plants) + 1

= (4800 m ÷ 9.6 m) + 1

= (48001÷9610) + 1

= (48001×1096) + 1

= 500 + 1

= 501

∴ Total number of trees planted on both sides of the road = Number of trees planted on each side of the road × 2 = 501 × 2 = 1002

Thus, the number of trees planted on both sides of the road is 1002
