📏 Topic Summary
Area is the measure of the amount of surface a two-dimensional shape covers. It's always expressed in square units (e.g., square inches, square meters). Understanding how to calculate the area of basic shapes like squares, rectangles, triangles, and circles is fundamental to geometry. This practice test will help you assess your understanding of these core concepts.
To succeed, remember the basic formulas: for a rectangle, it's length times width; for a triangle, it's one-half times base times height; and for a circle, it's pi times the radius squared. Let's put your knowledge to the test!
🧩 Part A: Vocabulary
Match the terms with their correct definitions:
| Term | Definition |
|---|---|
| 1. Area | A. A quadrilateral with four right angles and opposite sides equal. |
| 2. Rectangle | B. The distance around a circle. |
| 3. Radius | C. The measure of the surface enclosed by a shape. |
| 4. Circumference | D. Half the diameter of a circle. |
| 5. Square | E. A quadrilateral with four equal sides and four right angles. |
✍️ Part B: Fill in the Blanks
Complete the following sentences:
- The area of a rectangle is calculated by multiplying its ______ by its ______.
- The area of a triangle is equal to one-half times the ______ times the ______.
- The formula for the area of a circle is $$\pi$$ times the ______ squared.
🤔 Part C: Critical Thinking
Explain how the formula for the area of a rectangle can be used to derive the formula for the area of a parallelogram.
