Use this diagonal of a rectangle calculator and find the answer to the l - length,; w - width,; α - angle between diagonals,; r - circumcircle radius, area and diagonal of every square you want, just from the length of its side. Other links. What is the length of the diagonal of a rectangle that is 3 feet long and 4 feet wide ? We also know the area, so we write an equation and solve for x: . to that of the diagonal of a rectangle with length and width 18 and 36, so its length can be . To find the diagonal of a rectangle formula, you can divide a rectangle into two congruent right trianglesi. Each triangle will have sides of length l and w and a hypotenuse of length d. You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: Our diagonal of a rectangle calculator allows you to use almost any units you want. Check out our length converter or area converter to find out how to switch between different units SI and imperial. What's the diagonal of a rectangle formula? Sometimes you won't have given all of two rectangle's sides. How to find the diagonal of a rectangle in that situation? The answer is provided with our diagonal of a rectangle calculator. At first, let's write down three basic equations, for the areaperimeter and circumcircle radius: Area of a rectangle: With the above equations, we can now derive various diagonal of a rectangle formulas that are used by this diagonal of a rectangle calculator: Given length and width: Also, remember that the diagonal of a rectangle calculator assumes that the length is longer than the width!
