a/b+b/d=ad+bc/cd
Lienar Measure of rectangles
Side A = Area/Side B
Perimeter =
Sum of all sides of an object
Area =
Width X Depth/Height
Area of a triangle =
Height X Base(Width)/2
What type of house would use triangular measurement
A frame house
Square foot-to-acre conversion
SF = # of Acres X 43,560
Volume =
Width X Height X Depth (assuming 90 degree angle)
Base =
Height X Depth / Volume
Different Denominators
a/c+b/d= ad+bs/cd
1 acre lost cost $230 per frontage foot; If it costs $100,000 total what was the depth of the lot
$100,000 / $250 = 400
43560/400 = 108.9
A salesperson sells 3/4 of an acre for $80,000, and receives a 7% commission. If she splits with her broker 50-50 (broker to agent), what did the salesperson receive in commission per square foot to the nearest cent?
9 cents per square foot
3/4 X 43,560 = $32,670 SF
Commission = ($80,000*7%)/2 = $2800
32,670/$2800 = $0.0857 per SF
A seller leaves a buyer approximately one half of a tank of heating oil at the closing. If the tank measures 4’ x 2’ x 3’, how many cubic feet did the buyer receive?
24 cubic feet
423 = 24
Andre owned a 1/4 acre lot. He wanted to construct a 120’ x 80’ tennis court on the lot. What approximate percentage of the lot will be left over, if any, when he has completed the construction?
11.8% will be left
43,560*1/4 = 10,890 (lot in SF)
120*80=9600 (area of the tennis court)
10,890 - 9600 = 1290 SF
1290/10,890 = 11.8%
The walls of these rooms were all 10’ high. The wall lengths were 16’, 20’, 16’, and 20’. If a gallon of paint covers 200 SF, how many whole gallons would the homesellers have to buy?
1016 + 1020 + 10 +16 + 10+20 = 720
720/200 = 3.6
4 GALLONS
