Exploring Shapes and Space

Geometry deals with points, lines, shapes, angles, and space. You'll often find questions about the area and perimeter of shapes.

Area and Perimeter

• Area: How much space a shape covers.
• Perimeter: The distance around a shape.

Common Formulas

• Rectangle area: \( A = l \times w \)
• Rectangle perimeter: \( P = 2(l + w) \)
• Triangle area: \( A = \frac{1}{2}bh \)

Everyday Uses

Geometry helps with tasks like painting a wall, building a fence, or buying new carpet.
