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 in

Area is the space covered by a two-dimensional shape. The two dimensions are often expressed in terms of length and height or length and width. Multiplying length by height gives the area of rectangular objects. If these objects are measured in feet, the area is in square feet.
