The **area** of a rectangle measures the amount of surface it encloses, expressed in square units. It equals the product of the length and the width:

$$A = L \cdot W$$

For example, a rectangular rug that is $$2$$ feet long and $$3$$ feet wide covers $$2 \cdot 3 = 6$$ square feet — exactly the number of unit squares that tile the surface. When the area and one dimension are known, the missing dimension can be found by dividing the area by the known side length.

Question:
Write the formula for the area of a rectangle. State what each variable represents.

Sample answer:
$$A = L \cdot W$$, where $$A$$ is the area, $$L$$ is the length, and $$W$$ is the width.

Key points:
- Uses $$A = L \cdot W$$
- Identifies $$A$$ as area
- Identifies $$L$$ as length
- Identifies $$W$$ as width

Feedback:

Question:
What is the area of a rectangle? Give its formula and the type of units used.

Sample answer:
Area is the amount of surface inside a rectangle. The formula is $$A=L\cdot W$$, where $$L$$ is length and $$W$$ is width. Area is measured in square units.

Key points:
- Area measures the surface inside a rectangle.
- The formula is $$A=L\cdot W$$.
- Area is reported in square units.

Rubric:
The response correctly defines area, gives the rectangle area formula, and states that area uses square units.
