After multiplying the length and the breadth, you get the final answer. Step 2: After converting the units, apply the formula of the area of a rectangle, i.e., l*b. Step 1: Before starting, convert the dimensions of length and breadth from the data. Multiply the base and height or use an area of the parallelogram calculator. Since the length is given as 4cm, we can substitute L with 4. Steps to Find the Area of a Rectangleīesides the rectangle area, the area of a parallelogram can be calculated using its base and height. To solve this, we start with the formula for the area of a rectangle, A equals to LW.
The area of a rectangle is always measured in square units. Hence the formula of the area of a rectangle is defined as A = l*b. 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 :
#Equation for rectangle area 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. We know that \(\bigtriangleup\)ABD and \(\bigtriangleup\)ACD are congruent triangles.Geometry is one of the most important topics in Mathematics, which deals with various shapes such as square, rectangle, etc. \(\bigtriangleup\)ABD and \(\bigtriangleup\)ACD. Now, let diagonal AD divide rectangle into two right triangles, i.e. Let us try to derive this formula of rectangle. Therefore, the area of the rectangle is equal to the sum of the area of these two triangles. The diagonals of a rectangle divide it into 2 equivalent right angled triangles. Why Area of Rectangle is Length into Breadth? There are two diagonals of equal lengths in a rectangle that can be calculated as: How to Calculate Area of Rectangle Using its Diagonal?ĭiagonal of rectangle is the straight line connecting its opposite corners or vertices. the product of its length and breadth in square units.Įxample: Calculate the area of rectangle if it is 9m wide and 4m high.Īrea of rectangle will be its length multiplied by its breadth Multiply length and breadth dimensions.Note the dimensions of length and breadth of the given rectangle.To calculate the area of rectangle, you have to follow the steps below.
