If a rectangle has a width of 42 inches and an area of 1638, how many rectangles of the same size would reach a length of 390 inches?
The rectangle has a length of 1638 in/ 42in = <T>divide(1638, 42)=39.0 in.
The number of rectangles required to reach 390 inches is 390/39 = <T>divide(390, 39)=10.0 rectangles.
