To calculate the area of a structure or section of land mass in square miles, use the formula for area of the section's shape with the dimensions, such as length, width, and radius, in miles. Not all sections of land or buildings have a simple shape, in which case the section should be divided up into simple shapes as well as possible to get an exact answer or a good estimate.
Know MoreThe area of a simple square plot of land can be calculated by measuring one side in miles and squaring that number. Simple formulas for area for triangles, circles, rectangles, parallelograms and other shapes can also be used when appropriate to calculate area.

The general usage of a T-square takes only a few minutes and requires the T-square, paper, a pencil and a drawing board. A square, triangle or French curve may be necessary for other shapes.
Full Answer >The formula to calculate the square footage of an area that is square or rectangular in shape is length multiplied by width equals the area's square footage. For example, if a rectangular shaped room measures 11 feet in length and 13 feet in width, 11 multiplied by 13 equals 143 square feet.
Full Answer >The square footage of a house is found by multiplying length times width, so a house that is 30 feet by 40 feet measures 1,200 square feet, assuming the house has only one story. The square footage of additional stories should be added as part of the total square footage.
