Perimeter

The perimeter is defined as the total length of the boundary of a two-dimensional shape or figure. It represents the distance around a closed shape, obtained by adding up the lengths of all its sides. Understanding perimeter is fundamental in geometry and is frequently used in practical applications such as fencing a yard, framing a picture, or calculating the amount of trim needed for a room. It's a linear measurement, expressed in units like meters, feet, inches, or centimeters, depending on the size of the shape being measured.
