And define another function called area() to calculate area of that rectangle. So we can make a class called Rectangle with two attributes l and b for length and breadth respectively. References:įrom the source Wikipedia: Rectangle, Characterizations, Classification, Properties, Formulae, Theorems, Crossed rectangles, Other rectangles.Suppose we have taken length and breadth of two rectangles, and we want to calculate their area using class. Where the value of ϕ is approximately 1.618. The formula to find the golden ratio of the rectangle is as follows: The rectangle whose side lengths are in a golden ratio. That's why always rectangles are not square. Their adjacent sides may or may not be equal. The rectangle’s opposite sides are equal but parallel to each other. Both opposite-sided diagonals have the same lengthĪ square is always a rectangle and the rectangle is not always a square.Each diagonal of the rectangle bisects the other.The sum of all angles is equal to the 360 degrees.Opposite sides of the rectangle are equal and parallel to each other.It is rectilinear which means that all sides meet at 90 angles.All corner angles are equal to each other.It's center is equidistance from its vertices so it is circumcircle.There are several properties of a rectangle that are as follows: Choose a unit in which you want to calculate area.The length of one side of the rectangle.Stay focused on the following points to understand the working of our area of shaded rectangle calculator. The diagonal of a rectangle formula is as follows ĭ = 6.326cm Working of Rectangle Area Calculator: P = 10cm Find The Diagonal Of a Rectangle:Ĭalculate the diagonal of a rectangle for the same rectangle that we suppose upper. Here we find the perimeter of the same rectangle that we suppose in the example. L = 4cm Find The Perimeter of a Rectangle We can also find the length or width by adjusting the rectangle area formula as follows: Put values in the formula to find an area of rectangle Suppose that a rectangle has a length of 4cm and a width of 6cm. The best feature of our rectangular area calculator is that if you have an area and want to calculate its length or width you can do so. It uses the following units to represent the area of a rectangle. You can calculate the area of a rectangle with the help of the rectangle area calculator. By using the area of the rectangle calculator, you can find a rectangle's area, perimeter, and diagonal. Area of a Rectangle Formula:Ī rectangle is a four-sided polygon that has four angles of 90 degrees. In a rectangle, the alternate sides are equal and parallel to each other. What Is a Rectangle?Ī rectangle is a type of quadrilateral with four sides, four corners, and four angles that are equal to 90 degrees. With the help of a maximum area of a rectangle calculator, you can find the area of the given coordinates of four corners of a rectangle as well. Our rectangle area calculator finds the area, perimeter, and diagonal of a rectangle by considering its lengths and width.
