Question 1020399: A rectangle parking space is m feet wide and n feet long. In the new design for the parking lot, each space will have its width increased by 1 foot and its length by 20%.
a.) Write a polynomial to represent the area of the new parking space.
b.) Shoshanna says that the area of each new parking space is 20% larger than the area of the old parking space. Is this correct? Use the polynomial you wrote in part A to explain why or why not.

Current parking spot AREA is mn.

The new parking spot AREA will be %28m%2B1%29%281.2%2An%29.
Simplification:
1.2mn%2B1.2n

Look at the factorization for either New Parking Spot Area. Shoshanna is correct.
