Common formulas: rectangles (Length x Width), triangles (1/2 x Base x Height), circles (pi x Radius²). For irregular shapes, divide into regular shapes and add them up. Land conversions are frequently tested: 1 acre = 43,560 sq ft, 1 section = 640 acres = 1 square mile, 1 township = 36 sections.
A rectangular lot measures 150 feet by 200 feet. Area = 150 x 200 = 30,000 square feet. To convert to acres: 30,000 / 43,560 = 0.689 acres. If land sells for $5/sq ft, lot value = 30,000 x $5 = $150,000.
Memorize that 1 acre = 43,560 square feet and 1 section = 640 acres. For irregular lots, practice breaking them into rectangles and triangles. Always double-check your units—don't mix feet and inches or square feet and acres in the same calculation.

IRV stands for Income, Rate, and Value. It represents the relationship between Net Operating Income (I), Capitalization Rate (R), and Property Value (V).
Net Operating Income (NOI) is the revenue a property generates after deducting all operating expenses.
The gross rent multiplier (GRM) is a quick method for estimating the value of income-producing property by multiplying the property's gross rent by a factor derived from comparable sales. GRM = Sale Price / Gross Rent.
The capitalization rate (cap rate) is the ratio of a property's net operating income to its sale price, expressed as a percentage. It is used to estimate value and compare profitability of investment properties. Cap Rate = NOI / Value.
