Square footage is the unit of measurement used to describe the entire surface area of a two-dimensional space. Determining square footage depends on the shape of the surface and involves manipulating measurements of its length and width.
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
Calculating square roots can either be done by hand or with a calculator. With a calculator, calculating a square root is as easy as pressing the number followed by the square root sign. These numbers are often long and are in decimal form.
To estimate a square root without a calculator, determine the two perfect squares that come before and after the given number. Then using the square roots of the perfect squares as guides, estimate the given number’s square root based on its placement between the two perfect squares.
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.
To calculate square meters in a given space, you can measure the number of meters on each side and multiply them. Alternatively, if you know the number of square feet, you can convert that figure into square meters. You may want to use a calculator to do the math involved.
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.
To calculate cost per square foot, divide the purchase price of a house by its total square footage. For instance, if a house with 2,000 square feet sells for $180,000, the cost per square foot is $90 per square foot.
To calculate the square meterage of a rectangular area, multiply the height in meters by the width in meters. The resulting number represents how many square meters of geometric space are contained in an area, including all contained space. This is a multi-dimensional area calculation.
To calculate the square root of a number in Microsoft Excel, enter "=SQRT(number)" into a blank cell. You can also set up side-by-side columns using the Excel worksheet function, where you can enter a number in one column and the square root appears in the column next to it.
