The area of a rectangle is
A= l(w)

You're given:
41 2/3 = l(4 1/4)

turn to decimals to make easier

41.666667 = l (4.25)
divide both sides by 4.25
l = 9.80392

well you know that the answer will start with 9 
then just find the decimals of fractions 
41/51 = .80392

boom first try

Answer is A 9 41/51
