  3. How many sheets of drywall do you need to sheetrock your garage? (1 sheet = 32 sq ft)

  4. Which floor refinisher’s bid is best for you?

  5. Don’t say you’re not good at math! All you need to be a smart homeowner is to be able to calculate the square footage of a rectangle.

  6. 2 rectangles rectangle 2 triangles = 1 rectangle

  7. 1 parallelogram = 1 rectangle Trapezoid: Average top and bottom and you have a rectangle

  8. CAN’T REMEMBER YOUR FORMULAS FROM GEOMETRY CLASS? Check out:www.math.com > Geometry > Area Formulas

  9. Now back to your floor refinishing problem… Let’s say you hire the refinisher who gave you the lower price ($2.00/sq ft) to sand, stain, and apply 2 coats of polyurethane to your livingroom , which measures 15 ft wide by 22 ft long.

  11. So your buddy comes over after work and you’re up until midnight moving your furniture. Over the next week you go to a chiropractor three times ($225.)
