Rectangle Quadrilaterals Square CalculatorGeometry Index Rectangle is a four sided polygon where the opposite sides are parallel and equal in length. Length is the measurement of extension of an object. Here it refers to the longest side of the rectangle. Rectangle has two diagonal which are equal in length and intersecting at the middle. All interior angle in rectangle equals 90 degree. You can use this online length of a rectangular calculator to find the rectangle length by providing the width and perimeter as inputs. Find the Length of a Rectangle Given PerimeterRectangle is a four sided polygon where the opposite sides are parallel and equal in length. Length is the measurement of extension of an object. Here it refers to the longest side of the rectangle. Rectangle has two diagonal which are equal in length and intersecting at the middle. All interior angle in rectangle equals 90 degree. You can use this online length of a rectangular calculator to find the rectangle length by providing the width and perimeter as inputs. Code to add this calci to your website Formula:L = (P/2) - w Where, L = Length of a Rectangle P = Perimeter w = Width ExampleA rectangle has its perimeter as 20 m and width as 5 m.

By simply inputting the length and width, this calculator will almost instantly find the perimeter (P) and the area (A). If interested in calculators for a variety of other shapes, you can look at more of our handy calculators. But you can stick around here and learn more about finding the area of a rectangle. A rectangle has four 90 degree angles. If the lengths of the sides are all the same, then the rectangle is also a square. The lengths of the sides will be given as a or b or you can use l and w for “length” and “width”. 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. Here are the basic formulas used by the calculator. Area(A) = a(b) Perimeter (distance around the outside of the rectangle) = a + a + b + b or 2a + 2b and is noted as (P) Diagonal is d² = a² + b² which is the Pythagorean Theorem (see our Pythagorean Theorem calculator). Example of calculating the area of a rectangle: Suppose the length is a = 6 inches and the width is b = 4 inches A = a*b , so A = 6(4) = 24 inches² Using the same dimensions, we can calculate the perimeter. The perimeter is 2a + 2b, so in this example the perimeter P = 2(6) + 2(4) = 20 inches To find the diagonal using the same dimensions: d² = 6² + 4² = 36 + 16 = 52 Take the square root of both sides and the diagonal d is approximately 7.2 inches These examples illustrate how to calculate the area, perimeter, and diagonal of a rectangle manually, but if you prefer to use the calculator for quicker results or to merely check your work, then feel free to do so. A great feature of the calculator is that you can find either the length or the width if you know the perimeter and the length of one of the sides. Area, Perimeter, and Diagonal of a RectangleThis page will show you how to deal with measuring the area of a rectangle. We will cover the following topics: What is the area, perimeter, and diagonal of a rectangle? How to calculate the area, perimeter, and diagonal of a rectangle? Real-life application in calculating the area, perimeter, and diagonal of a rectangle Area of a RectangleImagine the area of a rectangle as boxes inside a rectangle. The rectangle below has a covered area of 12 “square units” The space inside a two-dimensional shape is the area or the amount of covered shape. This diagram displays the width, length, and area of a rectangle: Calculating the Area of a RectangleTo find the area of a rectangle you need to multiply the length and the width of a rectangle. We can get the area of a rectangle by following this formula: A = L * W A is the area, L is the length, and W is the width. Example 1Calculate the area of a rectangle that has a length of 7 centimeters and a width of 5 centimeters. Formula:A = L * W Answer:A = 35. The given length (L) is 7 and 3 is the width (W). When multiplied, you will get 35 as your area. Perimeter of a RectangleTake a look at the image below, a person is walking around the box. The path he walks around from the starting point and back is the perimeter. Knowing the length and width of a rectangle, we can now get the perimeter of a rectangle. Both opposite sides of a rectangle are congruent which means adding those sides, we can calculate for the perimeter.
