Example Question #83 : Plane Geometry
Steve's bedroom measures 20' by 18' by 8' high. He wants to paint the ceiling and all four walls using a paint that gets 360 square feet of coverage per gallon. A one-gallon can of the paint Steve wants costs $36.00; a one-quart can costs $13.00. What is the least amount of money that Steve can expect to spend on paint in order to paint his room?
Two of the walls have area 
Therefore, the total area Steve wants to cover is
Divide 968 by 360 to get the number of gallons Steve needs to paint his bedroom:
Since 
The first option will cost him

Example Question #52 : Quadrilaterals
Above is a figure that comprises a red square and a white rectangle. The ratio of the length of the white rectangle to the sidelength of the square is 
To make this easier, we will assume that the rectangle has length 5 and the square has sidelength 3. Then the area of the entire figure is
and the area of the square is
The square, therefore, takes up
of the entire figure.
