## What is Area

Area measurements indicate the total size of a 2 dimensional shape. Put another way, area is the amount of space within the boundaries of 2 dimensional shapes, such as a rectangle or square. When finding area, it is crucial to use the same unit of measure for all measurements. Area measurements are commonly used for construction material estimates and to identify property sizes.

## Common Area Formulas

Area is commonly found by multiplying the length of a space by the width of a space. That assumes that the space is square or rectangular. Calculating the area of a border involves subtracting the area of the inner space from the area of the outer space to find the remaining area of the border. Finding the area of a circle or triangle requires a different formula altogether. Check out the formulas below to find out how to calculate the area of a shape. Check out our square footage calculator to find the square footage of an area.

### Rectangular Border

outside area = length x width inside area = (length - (2 x border)) x (width - (2 x border)) border area = outside area - inside area## Units of Area Measurement
