Multiply To Find Area
Standard(s): 5.NF.B.4.B
Lin and Tyra are measuring the area of the piece of paper shown below. Lin multiplied the length times the width to find an answer. Tyra traced the paper onto 1-inch graph paper and counted the number of squares. How should their answers compare?
Lin’s answer will be a mixed number, but Tyra’s will be a whole number.
Tyra’s answer will be greater than Lin’s answer.
Lin’s answer will be greater than Tyra’s answer.
They should end up with almost exactly the same answer.

Description: Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.

Jeremy found that it takes 14 centimeter cubes to cover the surface of a rectangular image. Which of these measurements could possibly be the length and width of the rectangle he covered? Assume that centimeter cubes can be cut so that fractional measurements are possible.
Length = 3 ½ cm, width = 4 cm
Length = 4 ½ cm, width = 3 cm
Length = 7 cm, width = 7 cm
Length = 7 cm, width = 3 cm
