The drag force F on a boat varies jointly with the wet surface area A of the boat and the square of the speed s of the boat. A boat with a wet surface area of 50ft2 traveling at 7mph experiences a drag force of 98N. Find the wet surface area of a boat traveling 7.5mph and experiencing a drag force of 135N.
