Unit 1 - Item 2
Alex has a garden that is in the shape of a rectangle. Its length is twice its width. He decided to make a larger garden that was 5 feet longer and 3 feet wider than his original garden.
If x represents the original width of the garden, what expression represents the difference between the area of his new garden and the area of the original garden?
Draw a visual representation of the two gardens and explain your results.

Davis is designing a new office building. The architect presented him with two floor plans to choose from. Davis's goal is to maximize the size of the conference room.
Details about Plan A
The offices will have the same dimensions
The hallway is 4 ft wide
The dimensions of the exterior walls can be represented by the expression 9x + 4ft by the expression 15x ft
The length of the conference room is the same as the length of two offices
Office 1 and Office 2 have the same dimensions, 6x ft by 4x ft.
Office 3 and Office 4 have the same dimensions, 5.5x ft by (x+4) ft.
Unit 1 – Item 8
Explain how Davis should go about determining which floor plan results in the biggest conference room? Be as detailed as possible.
Unit 1 – Item 9
Using the information above in Item 8, write an email to Davis explaining which floorplan he should choose and why.
