From this find out Side(a)DiagonalPerimeterArea of the square.

SolutionSquare FormulaArea Formula
 Area of Square Diagonal (d) = sqrt(2) aPerimeter (P) = 4aArea (A) = a^2 = d^2/2Example : I know that for a square Side(a) = 10 . From this find out Area of the square."Here a" = 10" (Given)""Diagonal" = sqrt(2) * "a" = sqrt(2) * 10 = 14.1421"Perimeter" = 4 * "a" = 4 * 10 = 40"Area" = "a"^2 = 10^2 = 100
