perimeter of a rectangle
Perimeter of a rectangle
The online calculator allows to calculate the perimeter of a rectangle from its length and its width.
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.
Calculating perimeter of a rectangle
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`).
Symbolic calculation of the perimeter of a rectangle
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.
Syntax :
perimeter_rectangle(length;width)
Examples :
perimeter_rectangle(`3;2`), returns 12
