A square is a regular polygon with four sides. It has four right angles and parallel sides.
To calculate the area of a square, multiply the base by itself, which can be expressed as side × side. If a square has a base of length 8 inches its area will be 8 × 8= 64 square inches
Area of a square is given by:
A = a2
where a = length of side
Perimeter of a square = 4a
Diagonal of a square = (a)(sqrt(2)) or 1.414 (a)
Sorry if thats wrong o.o
