The length of a rectangle is one less than twice its width. The area of the rectangle is 120
square inches. We want to find the dimensions of the rectangle.
(a) Write a quadratic equation that could be used to solve this problem. [4 points]
Don’t solve your equation YET; just write it and circle or box it. Solve it in part (b).
(b) Use the equation you found in part (a) to find the dimensions of the rectangle.
(Hint: Factor or use the quadratic formula.) [4 points]
If your answer is not an integer, round to two decimal places.
Give your final answer in a phrase or sentence, and include appropriate units.
(c) In part (b), you should have found two solutions to your equation from part (a).
How did you know which one was the correct solution for this problem?
Explain your answer briefly. [
