Area and perimeter: word problems

Key Notes :

Area Word Problems:

1. Identifying Shapes: Recognize the shape described in the problem (e.g., rectangle, square, irregular shape).

Calculating Area:

• Rectangles and Squares: Use the formula Area=length×width.
• Irregular Shapes: Break down the shape into simpler rectangles or squares, calculate their areas, and then sum them up.

Perimeter Word Problems:

1. Identifying Shapes: Understand the shape described (e.g., rectangle, square, closed irregular figure).

Calculating Perimeter:

• Rectangles and Squares: Use the formula Perimeter=2×(length+width)
• Irregular Shapes: Add the lengths of all sides of the shape.

Problem-Solving Strategies:

1. Read Carefully: Understand the problem statement and identify what information is provided and what is needed.
2. Draw Diagrams: Sketch the shape described in the problem, especially when dealing with irregular shapes.
3. Label: Label dimensions clearly on the diagram to avoid confusion.
4. Compute Correctly: Use the appropriate formulas for area and perimeter based on the given shape.
5. Check Units: Always check that the units in the final answer are appropriate and consistent with the problem context.
