# Area, Perimeter, and Diagonal of a Rectangle with Uncertain Sides

Area, Perimeter, and Diagonal of a Rectangle with Uncertain Sides

Using the uncertain calculus [1] and interval arithmetic, simple analytical solutions are derived and used to calculate the area, perimeter, and diagonal of a rectangle with the bottom left corner at the origin and the top right corner defined by dragging the locator. The slider value is added as an uncertain part to .
