# Perimeter Formulas

If an object occupies some space, its perimeter is the distance around the outer side of that object. It is usually defined as the total sum of the length of all the sides of a particular object. Therefore, the algebraic sum of the length of individual sides of the object gives the perimeter of that object.

The following provides information about a diverse range of perimeter formulas.

Perimeter of a Parallelogram Formula

The total distance outside the parallelogram is its perimeter. A parallelogram is a geometric shape that comes with four sides – the sum of the length of all four sides is the perimeter of a parallelogram. In a parallelogram, the opposite sides are always equal; therefore, the perimeter becomes twice the algebraic sum of the base and height of the parallelogram.

Perimeter of a Parallelogram Formula is given as,

Perimeter of a parallelogram=2*(Base+Height)

## Perimeter of a Rectangle Formula

The total distance of a rectangular geometric shape is called its perimeter. A rectangle has four sides, and to calculate its perimeter, you need to add the length of all the four sides together. In a rectangle, the opposite sides are always equal, which is why perimeter becomes twice the algebraic sum of the length and width of the rectangle.

Perimeter of a Rectangle Formula is given as,

Perimeter of a rectangle=2(Lenght+Width)

Where

a,b,c are sides of the triangle.

## Perimeter of a Triangle Formula

A triangle is a geometric shape that has three sides. The length of all three sides doesn't need to be equal. In case all three sides are equal, you're looking at an equilateral triangle. If only two sides are equal, it's an isosceles triangle. The perimeter of a triangle is the total distance outside the triangle, and to calculate it, you have to find the sum of the length of all sides.

Perimeter of a Triangle Formula is given as,

Perimeter of a triangle=a+b+c

Where

a, b, c are the sides of the triangle.

## Perimeter of a Square Formula

A square is a geometric shape that has four sides, all equal in length. Its perimeter is the total distance outside the square, which in other words mean that the sum of the lengths of all sides gives its perimeter. Since the sides are equal in length, its perimeter is four times the side of the square.

Perimeter of a Square Formula is given as,

Perimeter of a square=4a

Where

a is the side of the square
