What is Perimeter of a Rectangle?
Here, we are going to teach the perimeter of a rectangle. To understand this example, see the image given below. In the picture, we have to calculate the perimeter of that rectangle. What is a perimeter? First of all, we have to see: what is the size of the border of a rectangle here? That is called the perimeter of a rectangle.
How will we find out the perimeter of a rectangle? To find out the perimeter of any rectangle, first of all, suppose the long side of the rectangle is, we consider it A. After that, the short side of the rectangle is—suppose we consider it B. Here, first, we have to see how many feet, how many centimeters, or how many meters it is. So, suppose the long side of the rectangle is A = 8 feet. The short side of the rectangle is B = 4 feet. We have to do is use the formula here. P = 2 × (Length + width). the length is 8, and the width is 4. Here, we will not count the other two sides of the rectangle because they are equal. We will apply the formula here. Here, “A” is our 8 feet. A = 8. And B is our 4 feet. P = (8+4). Plus this, and then multiply it. First, we have to eliminate the brackets, so 8 + 4 = 12. P = 2 × (12). If we multiply this, P = 2 × (12) = 24. The boundary of the rectangle will be 24 feet.
Perimeter of a Rectangle Calculation Formula
Here, we will understand how to calculate the perimeter of a rectangle and also calculate the perimeter of a rectangle. First of all, we will need a formula to calculate the perimeter of a rectangle—the formula we have given below. The perimeter (P) of a rectangle is found by adding up all four sides. The formula is -
Perimeter of a Rectangle Calculation Example
Now, we will calculate the perimeter of a rectangle based on the Hi formula given above. For the perimeter of a rectangle, the formula requires two measurements of the rectangle we are given a rectangle with width = 100 cm and length = 200 cm.
Calculation –
P = 2 × ( l + w )
P = 2 × (200 cm + 100 cm)
P = 2 × 300 cm
P = 600 cm
The outline of the rectangle is 600 cm.
Thus for a given rectangle having a width equal to 100 cm and length equal to 200 cm then its perimeter would be 600 cm. It may be compared with the sum of distances around the rectangle and these distances are equal to 100 cm each, while the other two distances are 200 cm each.
Frequently Asked Questions (FAQ)
1. How big is a rectangle’s perimeter?
The perimeter is the sum length of all four sides of the rectangle together. The perimeter is the actual length of the boundary around the rectangle. To calculate the perimeter of the rectangle, the formula becomes perimeter = 2 x ( length + width ).
2. Why is it necessary for me to figure out a rectangle’s perimeter?
With the required values of width and length in mind, rimming out the total length border of the rectangle gives the perimeter. It is used in many practical tasks, such as garden fencing, painting framing, and planning room and furniture arrangements.
3. Can you use different units in the Perimeter of a Rectangle Calculator for width and length?
No, to avoid errors in the answer generated by the Perimeter of a Rectangle Calculator, it is advised to keep the same unit for length and width. Misleading results can occur due to the mixing of the units.
4. What will happen if both dimensions are equal?
Where length and breadth are equal, that rectangle is a square. Perimeter is measured using the same formula: 4 x Side, wherein Side is the length of any one of its edges. The alternate formula becomes P = 2 x (L + W).
5. How can I change the units of the answer?
You can multiply by the conversion factor to get the answer in different units. For instance, if the perimeter is being found in meters but you want it in centimeters, simply multiply it by 100 since one meter equals a hundred centimeters.
6. Is the perimeter of a rectangle always greater than the area?
Not always. The relationship between perimeter and area shall depend upon the length and breadth of the rectangle. A more balanced rectangle, such as a square, could have an area same or larger than the perimeter, but a slender, long rectangle will have got higher perimeter than the area.
7. Is it impossible, just from its area, to determine the perimeter?
Not only knowing the area can find out the perimeter of the rectangle. You need the length and breadth for accurate calculations of the perimeter.
8. What is the simplest recollection of the perimeter formula?
When trying to remember the formula, think of the perimeter radius rectangle to be twice the length added to the breadth; two lengths and two widths would be covered if you strolled around these rectangles.
