The perimeter of a rectangle or square is the total distance around the outer edges of the shape.For a rectangle, the perimeter is calculated by the equation 2 x (length + width).For example, if a rectangle has a length of 8 inches and a width of 5 inches
Add the length and width: 8 + 5 = 13 inches
Multiply that sum by 2: 2 × 13 = 26 inches
For a square, all sides are equal, so the perimeter is calculated by the equation 4 x length
