It is defined as the product of the length and breadth of the rectangle. The space occupied by the rectangle in a 2D space is known as the area of that particular rectangle. Hence the perimeter of this rectangle is 50cm. After adding all the sides, the sum we get is the perimeter of the rectangle.įor example, A rectangle with length 15cm and breadth 10cm, we can apply the formula 2 (l+b), we get 2(15+10), i.e 2(25)= 50. Once you’ve measured all the sides, it’s time to add them up. In order to find the perimeter of a rectangle, we need to measure the sides of the rectangle.

How to Find the Perimeter of a Rectangle? Hence, equation 2 (l+b) represents the perimeter, where and b represents the length and breadth of the rectangle, respectively. Suppose p is the perimeter of a rectangle, l is the length, and b is the breadth, then the perimeter can be represented in the equation form as :
#Rectangle area formula plus#
Since the opposite sides of a rectangle are equal, the perimeter of a rectangle is twice the length of the rectangle plus twice the breadth of a rectangle. The perimeter of a rectangle can be defined as the sum of all four sides of a rectangle. With the help of Cuemath online learning classes, you can explore the different geometric shapes using visual simulations that will let you solve complex problems related to rectangles in the future. Hence it is vital to have strong fundamentals.
The rectangle is one of the simplest shapes to study, but questions related to a rectangle in concepts like Trigonometry and Calculus can be a bit complex. The word rectangle comes from the Latin word ‘rectangulus,’ which means right angle. The two sides which are longer are known as the length of the rectangle, while the shorter side is the breadth of a rectangle. The sides of the rectangle intersect with each other to form a right angle. The opposite sides of a rectangle are of the same length and parallel to each other, i.e., all the points are equidistant. What is a Rectangle?Ī rectangle is a 2D geometric shape that has four sides and four vertices or corners. But first, let us get started with some basic concepts. We will be studying how to find the area of a rectangle and calculate the perimeter of a rectangle. In this blog, we are going to explore the shape rectangle. These shapes are then used in problem-solving questions of various topics such as trigonometry, algebra, calculus, etc. It also helps us understand the different properties of these shapes. These types of geometric figures are referred to as composite figures.Geometry is one of the most important topics in Mathematics, which deals with various shapes such as square, rectangle, etc. Many geometric figures are made up of two or more common figures, and their areas can be calculated using a combination of the area formulas above. The area of an ellipse with semi-major axis, a, and semi-minor axis, b, is: The area of a regular octagon with side length s is: The area of a regular pentagon with side length s is: The area of a regular hexagon with side length s is: The area of a kite, or rhombus, with diagonal length d 1 and d 2 is: The area of a trapezoid with bases, b 1 and b 2, and height, h, is: The area of a parallelogram with base, b, and height, h, is: The area of a rectangle with length, l, and width, w, is: The area of an equilateral triangle with side length, s, is: Where a, b, and c are side lengths, and Equilateral triangle
If the side lengths of the triangle are given, the area can be found using: The area of a triangle with base, b, and height, h, is: The exact area of many common shapes can be calculated using well-defined formulas. The area of a two dimensional shape or geometric figure is the space contained within its perimeter. Home / geometry / area and perimeter / area formula Area formula
