Rectangle Perimeter
A rectangle is a quadrilateral with four right angles and two equal opposite sides. The dimensions of the rectangle are defined by the lengths of its sides, which are most often denoted by the letters a and b. If all sides of the rectangle are equal, it is called a square.
The perimeter of a geometric figure is the total length of the boundaries of a flat geometric figure. The perimeter has the same dimension as length. If you need to calculate the perimeter of a rectangle, you can do it manually (twice the sum of two sides) or use the online calculator available on our website. Of course, the second method is much more convenient and faster.
Using the online calculator, you can very quickly and accurately calculate the perimeter of a rectangle. To do this, enter the values of both sides of the rectangle, after which the calculator will provide the desired result, i.e., the perimeter of the rectangle.
