Example Problem
Calculate the area of a rectangle with a length of 6 cm and a width of 4 cm.
Step 1: Identify the Problem
Define the problem: calculate the area of a rectangle. Understand the constraints: length = 6 cm, width = 4 cm.
Step 2: Understand the Problem
Gather information: the formula for area is length × width. Analyze the problem: identify the values for length and width.
Step 3: Plan a Solution
Brainstorm possible solutions: use the formula for area. Evaluate and select the best solution: use the formula with the given values.
Step 4: Implement the Solution
Plug in the values: Area = 6 cm × 4 cm. Calculate the area: Area = 24 cm².
Step 5: Test and Evaluate the Solution
Test with different values: try length = 3 cm and width = 5 cm. Evaluate the results: Area = 15 cm² (correct!).
