The design changes she must make to keep it afloat for a longer period of time is the use larger piece of paper..

Air resistance

This is the opposition to the  motion of an object in air. Air resistance increases with increase in surface area of the object.

A parachute with a large surface area will experience more air resistance and will float long in air before dropping, than a parachute with small surface area.
