Determining the square inches (also written as in
) in any two-dimensional area is usually a fairly straightforward process. In the simplest cases, when the area in question is in the shape of a square or rectangle, the area in square inches is given by the equation
of the area to be measured.
Squares and rectangles have four straight sides - in the case of rectangles, opposite sides have equal lengths, while in the case of squares, all four sides are equal. Measure any one of the square or rectangle's sides to find a value for length.
of the area to be measured.
Next, measure either of the sides that touch the side whose length you just measured. This side should meet the first side at a 90 degree angle. This second measurement is your square or rectangle's width.
Since all four of a square’s sides are equal, the "length" measure you obtain for a square will be identical to the "width" measurement. In this case, you only need to measure one side.
Simply multiply your measurements for length and width to determine the area of your square or rectangular area in square inches.
Find the area of a circle with the equation Area = pi × r
To find the area of a circle in square inches, all you need to know is the distance from the center of the circle to its edge in inches. This distance is called the circle's
Once you find this number, simply substitute it for "r" in the equation above. Multiply it by itself, then multiply it by the mathematical constant
(3.1415926...) to determine the square inches within the circle.
So, a circle with a radius of 4 inches would have an area of 50.27 square inches, as this is the product of 3.14 x 16.
Find the area of a triangle with the equation Area = 1/2 b × h.
Convert your measurements to inches before making calculations.
To get your final answer in square inches, it’s easiest to provide any measurements required for the formula (such as length, height, or apothem) in inches. So, if the sides of your square are 1 foot each, convert that to 12 inches before making the area calculation. Here are conversion factors for common units of measurement:
1 foot = 12 inches
1 yard = 36 inches
1 centimeter = 0.3937 inches
1 meter = 39.3701 inches
