Dear student,

 a. Unfolded paper lands on the ground later, because it faces more air resistance due to the high surface area in contact with the air. This air resistance opposes the motion of unfolded paper, hence it lands later. Similar happens with the frogs with webbed feet, more surface area, more resistance and thus the frog with stretched webbed feet takes longer time to land. 
b. Advantages of having stretched webbed feet :
1. Can land on the ground more safely and slowly. 
2. They can jump much further with the stretched webbed feet.
