Perimeter
Perimeter: the perimeter are the lines around the border of a shape. A triangle has three straight lines. A square has four straight lines. The lines are at right angle and they are all equal in length. A rectangle is formed by connecting opposing straight, right angeled, lines.
The formula for the perimeter of a rectangle is
P = (L + W) × 2, P is the perimeter, L is the length, and W is width.
P = (L + W) × 2, P is the perimeter, L is the length, and W is width.
