![]() ![]() Now, substituting these values in the formula for perimeter, we will getĮxample 3: Find the area and the perimeter of a rectangle whose length is 24 m and width is 12m?Įxample 4: Find the area and perimeter of a rectangle whose breadth is 4 cm and the height 3 cm. Therefore, the dimensions are 5cm and 3cm. Note that the value of x must be positive and therefore in our case, the value of x is 2. We can substitute the expressions for length and width into the equation for area in order to determine the value of x. Since the area of a rectangle is given by: ![]() We know that the dimensions of the rectangle in terms of x: If its area is 15 cm 2, what are the rectangle's dimensions and what is its perimeter? Thus, the perimeter of the rectangle is 42 cm.Įxample 2: If a rectangle's length is 2x + 1 and its width is 2x – 1. Perimeter of the rectangle = 2(l + w) units The perimeter of a rectangle is the total length of all the four sides.Įxample 1: Rectangle has the length 13 cm and width 8 cm. A rectangle is 2-dimensional however, perimeter is 1-dimensional and is measured in linear units such as feet or meter etc. In rectangle, the distance around the outside of the rectangle is known as perimeter. Step3: Remember, the final answer should be in square units.įor example, in a rectangle with a length of 6cm and breadth of 5cm, the area is l*b, i.e., 6*5= 30 cm 2. 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. Steps to Find the Area of a Rectangleīesides the rectangle area, the area of a parallelogram can be calculated using its base and height. 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 : 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. Geometry is one of the most important topics in Mathematics, which deals with various shapes such as square, rectangle, etc. ![]()
