The online calculator allows to calculate the perimeter of a rectangle from its length and its width.

perimeter_rectangle online

The calculator is able to **calculate online the perimeter of a rectangle**.
The **perimeter of a rectangle** is given by the formula `2*(L+l)` where L represents the length and l the width of a side.
The **perimeter of a rectangle** is equal to the sum of the sides.
The length calculator supports numeric but also literal expressions.

The length calculator is able to calculate the perimeter of a rectangle, the calculated length is returned in exact form and in approximate form.

The **calculation of the perimeter of a rectangle** whose length is 3 and width is 2 is done
by entering the following formula
perimeter_rectangle(`3;2`).

The length calculator is able to do symbolic calculations or literal calculation. To calculate, for example, the perimeter of a rectangle whose length is 1+x and width is 1+y, just enter the following formula perimeter_rectangle(`1+x;1+y`) ,after calculating the result is returned.

perimeter_rectangle(length;width)

perimeter_rectangle(`3;2`), returns 12
