- box numbers
- underline the question
- cross out words you do not know
That is incorrect. You should circle key words to help you see the important information.
That is incorrect. You should box numbers to help you see the important information without going back and reading.
That is incorrect. Underlining the question helps you to find it when you are ready to use all of the information you have.

Which rectangle would be helpful in solving the following word problem?
Jack planted pansies in the flower box. The flower box is 1 ft. in width and 3 ft. in length. What is the area of the box?
That is not correct. To find the area, multiply the length by the width, or A \({=}\) l \({\times}\) w. Include the correct square unit of measurement.
That is not correct. Be sure to check the unit of measurement when you are solving for area.
That is not correct. You don't yet know the area, so this rectangle will not help. It is missing information and has the wrong area.

Shawn has a small pool in his backyard. It is 5 m wide and 7 m long. What is the area of his pool cover?
- 5 m \({+}\) 7 m \({=}\) 12 m
- 5 m \({+}\) 7 m \({=}\) 12 sq. m
- 5 m \({\times}\) 7 m \({=}\) 35 m
- 5 m \({\times}\) 7 m \({=}\) 35 sq. m
That is not correct. To find the area, multiply the length by the width, or A \({=}\) l \({\times}\) w.
That is not correct. Remember that A \({=}\) l \({\times}\) w and is measured in square units.

- 80 sq. cm \({+}\) 10 cm \({=}\) l
- 80 sq. cm \({\times}\) 10 cm \({=}\) l
- 80 sq. cm \({\div}\) 8 cm \({=}\) l
That is not correct. To find the length, divide the area by the width.
That is not correct. To find the length, you can divide the total area by the width.
That is not correct. To find the missing length measurement, you can divide the area by the width.
That is correct! To find the area, divide the total area by with width.
Manny has a license plate to put on his car. The length is 10 in. and the width is 6 in. What is the area of his license plate?
