MATH?

How much paintdo you need to re-do your bathroom?(1 gallon = 500 sq ft)

How many sheets of drywalldo you need to

sheetrock your garage?(1 sheet = 32 sq ft)

Which floor refinisher’s bidis best for you?

$2.00/sq ft

$2.25/sq ft(includes furniture

removal and return)

All you need to be a smart homeowner is to be able to calculate the square footage of a rectangle.

Don’t say you’re not good at math!

rectangle 2 rectangles

2 triangles = 1 rectangle

1 parallelogram = 1 rectangle

Trapezoid:Average top and bottom and you have a rectangle

CAN’T REMEMBER YOUR FORMULAS FROM GEOMETRY

CLASS?

Check out: www.math.com> Geometry> Area Formulas

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.

Your wife says, “Let’s do it! I checked math.com and it will only cost $66!”

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.)

The job gets done.

It looks great.

2 weeks later the bill comes.

So you’re back at www.math.com

15 X 22 = 330 sq ft

X $2. a sq ft = $660.

What have you learned?

1. Your wife should go to www.math.com/decimalplaces

2. Your floor refinisher doesn’t know that you checked www.math.com for the formula

3. For another $82.50, you could have saved 3 trips to the chiropractor
