From this find out LengthBreadthDiagonalPerimeterArea of the rectangle.

SolutionRectangle FormulaArea Formula
 Area of Rectangle Diagonal (d) = sqrt(l^2 + b^2)Perimeter (P) = 2(l+b)Area (A) = l bExample : I know that for a rectangle Length = 5 and Breadth = 12 . From this find out Area of the rectangle."Here one-Side " (l) = 5" and other-Side " (b) = 12" (Given)""Diagonal" = sqrt(l^2 + b^2) = sqrt(5^2 + 12^2) = sqrt(25 + 144) = sqrt(169) = 13"Perimeter" = 2 * "(sum of Sides)" = 2 * (5 + 12) = 34"Area = Product of Sides" = 5 * 12 = 60
