Understanding how to find the perimeter of a rectangle is a basic math skill that comes up in homework, exams, and real-world situations. If you’re seeing the question, “what is the perimeter of rectangle JKLM? 32 units, 44 units, 56 units, or 64 units,” you might be working through a multiple-choice problem or studying for a test. Let’s break down how to solve it and what you should consider.
The Perimeter Formula for Rectangles
The perimeter of a rectangle is the total length around the figure. To find it, you use the formula:
Perimeter = 2 × (length + width)
Each rectangle has two pairs of equal sides—two lengths and two widths. Adding up all sides is what the formula does efficiently.
What Information Do You Need?
Before you can find the perimeter of rectangle JKLM, you need to know its length and its width. Sometimes, these are given directly in the problem, or you might see them marked on a diagram. If you have a textbook question or a worksheet that lists only answer choices (like 32 units, 44 units, 56 units, 64 units), check for clues: are side lengths given in a diagram? Is there information in the text?
If no dimensions are given, you can’t directly calculate the perimeter—you’d need more detail.
Solving the Example
Suppose the rectangle’s length is 16 units and its width is 12 units. Plugging those numbers into the formula:
Perimeter = 2 × (16 + 12)
Perimeter = 2 × 28
Perimeter = 56 units
In this case, out of the answer choices, 56 units is correct.
Tips for Multiple-Choice Questions
- Carefully identify all given side lengths. Sometimes rectangles are drawn with one side labeled and the other implied.
- Double-check units. Make sure lengths and widths are in the same units before adding.
- Watch out for tricks. Some questions may list side lengths more than once, or include a “none of the above” option.
Common Mistakes to Avoid
- Miscalculating: Don’t forget to multiply the sum of length and width by 2.
- Mixing up area and perimeter: Area uses length × width; perimeter uses 2 × (length + width).
- Overlooking side measurements: If only one side is labeled, remember rectangles have two pairs of equal sides.
Practical Applications
Knowing how to find a rectangle’s perimeter isn’t just for passing tests. This measurement comes up when you need to buy a fence for a yard, install trim around a room, or estimate materials for a project.
Bottom Line
If the question is “what is the perimeter of rectangle JKLM? 32 units, 44 units, 56 units, or 64 units,” the correct answer depends on the given side lengths. Using the perimeter formula and double-checking your math, you’ll find the right answer—often 56 units if the sides are 16 and 12 units long. Always look for all the details, and you’ll solve rectangle perimeter questions with confidence.
