Area of a square calculator - formulas and calculator for calculating square area. Area of a square - is a numerical characteristic characterizing the size of a plane bounded by four series-connected segments (sides) of the same length, whose opposite sides are parallel in pairs, and the angle between any two adjacent sides is 90 degrees.
Different formulas are used to calculate area of a square, depending on the known input data. Below are formulas and a calculator that will help you calculate area or check the already performed calculations.
