Question

which expression represents the area of the tiny house? 30 ÷ 20, 30 + 20, 30 · 20, 30 − 20 (with an image of a tiny house floor plan labeled 20 ft and 30 ft)

Explanation:

Step1: Recall Area of Rectangle

The tiny house is a rectangle (implied by length and width). The formula for the area of a rectangle is \( \text{Area} = \text{length} \times \text{width} \).

Step2: Identify Length and Width

Here, length is 30 ft and width is 20 ft. So the area should be \( 30 \times 20 \) (or \( 30 \cdot 20 \)).

Step3: Evaluate Options

• \( 30 \div 20 \): Division, not for area.
• \( 30 + 20 \): Addition, for perimeter (sum of sides, not area).
• \( 30 \cdot 20 \): Multiplication, matches area formula.
• \( 30 - 20 \): Subtraction, not for area.

Answer:

\( 30 \cdot 20 \) (the option with \( 30 \cdot 20 \))
