Perimeter = 2(w + 3w) = 2(4w) = 8w = 64 → w = 64 / 8 = 8 meters

How to Solve Perimeter Problems Like a Pro: A Simple Step-by-Step Guide (With Example)

Understanding perimeter calculations is essential in geometry, whether you're measuring a garden, a room, or any enclosed space. Today, we’ll walk through a clear, practical example to help you master how to solve perimeter problems step by step.

Understanding the Context

Understanding the Perimeter Formula

The perimeter of a rectangle is calculated using the formula:

\[
\ ext{Perimeter} = 2 \ imes (\ ext{length} + \ ext{width})
\]

Given that one side (let’s say the width) is defined as \( w \), and the adjacent side is three times that width (\( 3w \)), we substitute into the formula:

Key Insights

\[
\ ext{Perimeter} = 2 \ imes (w + 3w)
\]

Step-by-Step Breakdown

Add the dimensions inside the parentheses:
\[
w + 3w = 4w
\]
Multiply by 2 to find the full perimeter:
\[
2 \ imes 4w = 8w
\]
Set the perimeter equal to the given value:
If the perimeter is 64 meters:
\[
8w = 64
\]

Final Thoughts

Solve for \( w \):
Divide both sides by 8:
\[
w = \frac{64}{8} = 8
\]

So, the width \( w = 8 \) meters.

Finding the Full Dimensions

Since the width is 8 meters and the length is \( 3w \):
\[
\ ext{Length} = 3 \ imes 8 = 24 \ ext{ meters}
\]

This confirms our rectangle has dimensions 24 m × 8 m, with a perimeter of \( 2(24 + 8) = 64 \) meters — exactly matching the problem.

Why This Method Works

This approach applies to any rectangle where one dimension is a known multiple of the other. By using the perimeter formula and substituting variables, you can quickly solve for unknown sides every time.
