✨$\underline{Here's\: ur \:answer}$

Aeroplanes and ships body have a streamlined shape because it reduces the amount of air drag / air resistance, thus allowing less amounts of energy to be wasted. For example, it cars were to be designed like trucks, this would increase friction, slowing the object down. Take the example of sports cars. They are streamlined so that when it flows through the air, the car can travel smoothly, not clumsly-like movements. Trying experimenting this with a parachute and you'll see why.
