Perimeter of a Parallelogram – Explanation & Examples

The perimeter of a parallelogram is the total length of its outer boundaries. A parallelogram, similar to a rectangle, is a quadrilateral with equal opposite sides. So if the length and width of a parallelogram are $a$ and $b$, such as in the figure above, we can calculate the perimeter as: Perimeter = $2(a + […]

Perimeter of a Rhombus – Explanation & Examples

The perimeter of a rhombus is the total length measured across its boundaries. All sides of a rhombus are equal to each other. If the length of any single side is equal to $x$, as shown in the figure above, then the perimeter is given as Perimeter $=4x$ We get the perimeter of a rhombus […]

Perimeter of a Square – Explanation & Examples

The perimeter of a square is the total length measured across its boundaries. Let $x$ be the length of each side of the square, as shown in the figure below: The perimeter is calculated using the formula: $textrm{Perimeter} = 4x$ The word perimeter is the combination of two Greek words, “Peri” meaning surrounding or enclosing […]

Perimeter of a Triangle – Explanation & Examples

The perimeter of a triangle can be defined as the total length across all the boundaries of a triangle. Let the lengths of three sides of a triangle be given as $a$, $b$ and $c$, as shown in the figure above. With this information, the perimeter is calculated as: $Perimeter = a + b + […]
