Answer:
The aeroplanes are streamlined in order to reduce the drag(friction in air) which results in more speed and consumption of less fuel.

Streamlined aeroplanes and natural streamlining
Explanation:
When an object or animal has a shape that minimizes resistance against air or water flow, it is said to be streamlined.
Aeroplanes are given a sleek and streamlined design to help decrease the resistance of air when they fly. this streamlining increases the speed and reduces fuel consumption in air-crafts.
We find streamlined shapes in nature for the same reason. Birds have streamlined bodies which help them fly with less air resistance. Fishes also possess streamlined bodies to help them move forward rapidly in the water bodies.
