![]() ![]() The following is the calculation formulas of the area, perimeter and diagonal of rectangle whose sides. In geometry, a rectangle is any quadrilateral with all four interior angles 90 (right angles). A rhombus is a quadrilateral with opposite sides parallel and all sides equal length. Calculations include side lengths, corner angles, diagonals, height, perimeter and area of a rhombus. Note: The angle α between diagonals is in the front of the length like in the first figure. The Rectangle Calculator is used to calculate the area, perimeter and diagonal of a rectangle. Calculate certain variables of a rhombus depending on the inputs provided. With the above equations, we can now derive various diagonal of a rectangle formulas that are used by this diagonal of a rectangle calculator:ĭ = √(2l² - P × l + P²/4)) or d = √(2w² - P × w + P²/4) ĭ = P / (2 × sin(α/2) + 2 × cos(α/2)) and Circumcircle radius of a rectangle r = d/2.Perimeter of a rectangle P = 2 × w + 2 × l,.First, let's write down three basic equations for the area, perimeter] and circumcircle radius: How to find the diagonal of a rectangle in that situation? The answer is provided with our diagonal of a rectangle calculator. Sometimes you won't have given the length of two adjacent sides of a rectangle. On the other hand, you can inscribe a circle into a rectangle only if it is a square. The center of a rectangle is equidistant from its vertices therefore, you can always circumscribe a circle on it. They can quickly estimate the perimeter, area, and diagonal of every square you want, just from the length of its side. Try our calculators dedicated to squares, e.g., the square calculator. Measure the length of the diagonal, area, and perimeter of a rectangle whose length is 4 units and width is 3 units. Its definition is that it has all four sides of equal length alternatively, the angle between two diagonals is right. Rectangle calculator will give the perimeter, area and diagonal length of a. Its opposite sides are parallel and of equal length, and its two diagonals intersect each other in the middle and are of equal lengths too.Ī square is a special case of a rectangle. Online calculator to calculate the surface area of geometric solids. This name derives from the fact that a rectangle is a quadrilateral with four right angles (4 × 90° = 360°). The term rectangle comes from the Latin rectangulus, which is a combination of two words: rectus (right, proper) and angulus (angle). And two other parameters which are not shown in the picture: ![]()
