#Formula for perimeter of a rectangle how to#

This is how the human body surface area was calculated as well: subject's bodies were covered in stripes of paraffin, which were then removed, sliced and measured. Irregularly shaped areas are often divided into several rectangles when one needs to calculate their area, but can't do a precise calculation. Practical applicationsĪrea of a rectangle calculations have a vast array of practical applications: construction, landscaping, internal decoration, architecture, engineering, physics, and so on and so forth. Since in multiplication the order in which the numbers are multiplied does not matter, you need not worry about switching the places of the two measurements. Plug in the values of the length and width in the formula P 2 (l + w), to compute the perimeter of the rectangles given as geometrical shapes in this set. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet. For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. Sum of all four sides of the rectangle can is termed its perimeter.The area of any rectangular place is or surface is its length multiplied by its width. Perimeter of a rectangle can be found by adding all the sides of it.

Question 2: How to find the perimeter of a rectangle? Simply, the perimeter of a rectangle is its total boundary of it. The perimeter of a rectangle can be defined as the total distance covered around the boundaries of a rectangle. Area of a rectangle can also be defined as the number of square units required to completely fill the rectangle. The area of a rectangle is defined as the space that is covered by a rectangle in a 2-D space. Question 1: What is meant by the area and perimeter of a rectangle? Therefore, the perimeter of a compost pit whose longest side is 100 cm and shortest side is 34 cm is 268 cm FAQs on Perimeter of Rectangle Shortest side = 34 cm, so breadth (b) will be the shortest side. Longest side = 100 cm, so length (l) will be the longest side. Therefore, the perimeter of a bed cot whose sides are 100 cm and 200 cm is 600 cm.Įxample 5: Find the perimeter of a compost pit whose longest side is 100 cm and shortest side is 34 cm. So, Substitute the both values in perimeter formula, So, Substitute both values in perimeter formula, Solved Examples on Perimeter of a RectangleĮxample 1: Find the perimeter of a rectangle whose length is 8 cm and breadth is 12 cm. Perimeter of rectangle is used in carpentry to determine the dimensions of the rectangular objects such as doors, tables, beds, etc.Construction of buildings and others requires determining the boundaries of the same which can be easily calculated using the perimeter formula.Perimeter of the rectangle is helpful in making the frames for the various objects.The length of a rectangular field or a garden for its fencing can be determined by using the perimeter formula.Perimeter of a rectangle can have many real-life applications.

Real World Applications of Perimeter of Rectangle Step 3: Solve the formula and the value obtained is the final Perimeter of the given figure. Step 2: Values of Length(l) and Breadth(b) are substituted in the formula. Step 1: For calculating the perimeter of a rectangle, the Length(l) and Breadth(b) of the given figure are noted Perimeter of a rectangle can be calculated in a few simple steps. Perimeter of a rectangle is 2(l + b) How to Find the Perimeter of a Rectangle?
