Perimeter of Parallelograms

We know four kinds of parallelograms. They are a square, a rectangle, a rhombus and a rhomboid. They have their own formulas to calculate their perimeters.

Topic NameFormula
Perimeter of SquareP = 4 × a
Perimeter of RectangleC = 2 × (a + b)
Perimeter of RhombusC = 4 × a
Perimeter of RhomboidC = 2 × (a + b)
