Rectangular Floors X and Y have equal area. If Floor X is 16 feet by 18 feet and Floor Y is 9 feet wide, what is the length of Floor Y, in feet?	Answers: A) 13 1/2 B) 18 C) 18 3/4 D) 21 E) 32
The area of a rectangle is: Area = length x width   We are given that floor X is 16 feet by 18 feet and that floor Y is 9 feet wide. So we can say:   length of X = 16   width of X = 18   width of Y = 9   length of Y = n   We also can say:   Area of Floor X = Area of Floor Y   (length of X)(width of X) = (length of Y)(width of Y)   (16)(18) = 9n   (16)(2) = n   32 = n   Answer 32.
