Introduction
Finding the perimeter of a rectangle is an essential math skill. This article is here to help you with a beginner’s guide on how to find the perimeter of a rectangle.
Perimeter of a rectangle is the distance around a rectangle, and it is equal to the sum of the lengths of its four sides. It may seem like a simple concept, but it can be tricky to get right. Remembering the formula, calculating the length of each side, and adding them up are just some of the steps involved in finding the perimeter of a rectangle. But don’t worry, by the end of this article, you’ll be able to find the perimeter of a rectangle with confidence!
Step-by-Step Guide: “A Beginner’s Guide to Finding the Perimeter of a Rectangle”
The first step in finding the perimeter is understanding the formula for perimeter, which is
Perimeter = 2 × (length + width)
This formula states that the perimeter of a rectangle is twice the sum of its length and width. So, let’s take a rectangle and go through the steps of finding the perimeter together.
If we have a rectangle with length 8 centimeters and width 5 centimeters, here is how we would find its perimeter:
- Multiply 2 by (8 + 5)
- 2 × 13 = 26 cm
Therefore, the perimeter of this rectangle is 26 centimeters.
Here’s a visual representation of this rectangle:
It is important to remember that the length and width will not always be given explicitly, and you may need to use the Pythagorean theorem to find the length of one of the sides.
