1. The problem is to match each formula to its corresponding term.
2. Here are the formulas and their meanings:
- Area of Triangle: $$A = \frac{1}{2} b \cdot h$$ where $b$ is the base length and $h$ is the height.
- Area of Circle: $$A = \pi r^2$$ where $r$ is the radius.
- Permutation: $$P(n,r) = \frac{n!}{(n-r)!}$$ which counts ordered arrangements.
- Surface Area: $$A = \text{add up area of all faces/surfaces}$$ total area covering a 3D shape.
- Combination: $$C(n,r) = \frac{n!}{r! (n-r)!}$$ which counts unordered selections.
- Area of Rectangle: $$A = b \cdot h$$ where $b$ is base length and $h$ is height.
- Volume: $$V = B \cdot h$$ where $B$ is the area of the base and $h$ is height.
3. Match each term to the correct formula:
- Area of Triangle: g. $$A = \frac{1}{2} b \cdot h$$
- Area of Circle: f. $$A = \pi r^2$$
- Permutation: c. $$\frac{n!}{(n-r)!}$$
- Surface Area: b. add up area of all faces/surfaces
- Combination: d. $$\frac{n!}{r! (n-r)!}$$ (note: original d had a typo, corrected here)
- Area of Rectangle: e. $$A = b \cdot h$$
- Volume: a. $$V = B \cdot h$$
4. Important notes:
- Factorials ($n!$) represent the product of all positive integers up to $n$.
- Permutations count arrangements where order matters.
- Combinations count selections where order does not matter.
q_count is 1 because only one distinct problem is solved here.
