Measurement Formulas for Real Estate
If you are preparing for the Real Estate License Exam, then you need to be aware of the importance of measurement formulas. The cost of a property is often linked to its area and perimeter. But each different shape has a different way of calculating its dimensions. That’s why Union Test Prep has prepared the following chart where you will find the equations needed to do the calculations required on the Real Estate Test. Practice using these equations by using our free study materials for the Real Estate Exam.

Area  \(A=\frac{1}{2}b \cdot h\)  A = Area of a triangle b = base h = height 

Area  \(A=s^2\)  A = Area of a square s = side length 

Area  \(A=l \cdot w\)  A = Area of a rectangle l = length w = width 

Area  \(A=h \cdot \frac{(b_1+b_2)}{2}\)  A = Area of a trapezoid \(b_n\) = base n h = height 

Area  \(A = \pi r^2\)  A = area of a circle r = radius 

Volume  \(V=l \cdot w \cdot h\)  V = Volume of a rectangular prism l = length w = width h = height 

Perimeter  \(P=s_1+s_2+s_3\)  P = Perimeter of a triangle \(s_n\) = side length 

Perimeter  \(P=4 \cdot s\)  P = Perimeter of a square s = side length 

Perimeter  \(P=(2 \cdot l)+(2 \cdot w)\)  P = Perimeter of a rectangle l = length w = width 

Perimeter  \(C=2\pi r\) or \(C=\pi d\) 
C = Perimeter of a circle r = radius d = diameter \(\pi\) = 3.14 

Pricing  \(PFF=\frac{SP}{FF}\)  PPF = Price per front feet SP = Sales Price FF = Front Feet 

Units  \(Du=Su \cdot \frac{Du}{Su} = Su \cdot CF\)  Du = Desired Unit Su = Starting Unit CF = Conversion Factor \(\frac{Du}{Su}\) 
Multiple steps may be needed. 
Units  1 ft = 12 in 1 yd = 3 ft = 36 in 1 rod = 16½ ft = 5½ yd 1 mi = 5280 ft = 1760 yd = 80 chains Checks = 24 x 24 mi Townships = 6 mi x 6 mi Sections = 1 mi x 1 mi Quarter Sections = 160 ac 
ft = feet in = inches yd = yard mi = miles ac = acres
