As shown above. Omit "the sides of". It's obvious that the houses are on the sides of the road and not on the road.

Why we didn't use" out of " could we use it or not please explain.And along shows the both sides ? I mean if houses are only on one side not the other or on both sides .

rashid rajalAnd along shows the both sides?

That would normally be assumed, but you can make it more explicit if you want.

Well now new thing.
4km of the 10km

10kg of the 15 kg.
How its works. Because the second one 5 people of 10 people dosnt sound good to me. Please explain

rashid rajal 5 people of 10 people dosnt doesn't sound good to me
