Question 1155186: Below is a floor plan for a combined living and dining area. The owners of the home have recently adopted a puppy, so the living room needs to be re-carpeted (bad puppy).
The total area for both rooms is expressed as: 2x^2+x+3 square meters. The tile in the dining room was already replaced, so we know the area of that room is: 2x^2-2x square meters.
Known area of dining room: 2x^2-2x square meters.
Area of combined dining and living room: 2x^2+x+3 square meters.
Find an expression for the area that needs to be re-carpeted.
After solving, choose the expressions that represent the length and width of the dining room, which can be found by completely factoring its area.

Area of combined dining and living room: square meters
the area that needs to be re-carpeted is
the living room area that needs to be re-carpeted is : ........factor it
the length of the dining room is and width is
