Applying the Approach to a Typical Algebra Problem

Let's assume the problem involves a scenario such as:

"A rectangle has a length that is 3 times its width. If the perimeter of the rectangle is 48 units, find the dimensions of the rectangle."

Here's how we would solve it step-by-step:

Step 1: Identify Known and Unknowns

• Known:


• Perimeter \( P = 48 \)


• Relationship between length and width: \( L = 3W \)


• Unknown:


• Width \( W \)


• Length \( L \)

Step 2: Define Variables

• Let \( W \) = width


• Let \( L \) = length

Step 3: Set Up Equations

• Perimeter of a rectangle: \( P = 2L + 2W \)


• Substitute \( L = 3W \) into perimeter:

\[
48 = 2(3W) + 2W
\]

Step 4: Simplify the Equation

\[
48 = 6W + 2W
\]
\[
48 = 8W
\]

Step 5: Solve for \( W \)

\[
W = \frac{48}{8} = 6
\]

Step 6: Find \( L \)

\[
L = 3W = 3 \times 6 = 18
\]

Step 7: Verify and Finalize

• Check perimeter:

\[
2L + 2W = 2 \times 18 + 2 \times 6 = 36 + 12 = 48
\]

• The calculations are correct.

Final Answer:

• Width = 6 units


• Length = 18 units
