Perimeter of a Rectangle
The perimeter of a rectangle is the total distance around its boundary. Because a rectangle has two pairs of equal opposite sides, traveling around the figure covers each length and each width twice. The formula is:
where is the length and is the width. Equivalently, the perimeter can be expressed as , since traversing the boundary means passing along all four sides once. When any two of the three quantities (, , ) are known, the third can be found by substituting the known values into the formula and solving the resulting equation.
