![]() ![]() Take the square root of both sides and the diagonal d is approximately 7.2 inches To find the diagonal using the same dimensions: The perimeter is 2 a + 2 b, so in this example the perimeter Using the same dimensions, we can calculate the perimeter. Suppose the length is a = 6 inches and the width is b = 4 inches Perimeter (distance around the outside of the rectangle) = a + a + b + b or 2 a + 2 b and is noted as (P)ĭiagonal is d² = a² + b² which is the Pythagorean Theorem (see our Pythagorean Theorem calculator).Įxample of calculating the area of a rectangle: Here are the basic formulas used by the calculator. The diagonal, which goes from one vertex to the opposite vertex cutting the rectangle into two squares, is called the diagonal and noted as d. The lengths of the sides will be given as a or b or you can use l and w for “length” and “width”. If the lengths of the sides are all the same, then the rectangle is also a square. But you can stick around here and learn more about finding the area of a rectangle.Ī rectangle has four 90 degree angles. If interested in calculators for a variety of other shapes, you can look at more of our handy calculators. If you need to find the area and perimeter of a rectangle, this calculator is the handy tool you will need.īy simply inputting the length and width, this calculator will almost instantly find the perimeter (P) and the area (A).
