Answer 1

To determine the original rectangle dimensions and area using the scale provided, we need to convert the length and width measured in scale units to feet.

1. **Original Length**:
- Given scale length = 7 units
- Each unit represents 0.25 feet.
\[
\text{Original Length} = 7 \, \text{units} \times 0.25 \, \text{feet/unit} = 1.75 \, \text{feet}
\]

2. **Original Width**:
- Given scale width = 3 units
- Each unit represents 0.25 feet.
\[
\text{Original Width} = 3 \, \text{units} \times 0.25 \, \text{feet/unit} = 0.75 \, \text{feet}
\]

3. **Original Area**:
- To find the area, we multiply the original length by the original width:
\[
\text{Original Area} = \text{Original Length} \times \text{Original Width} = 1.75 \, \text{feet} \times 0.75 \, \text{feet} = 1.3125 \, \text{square feet}
\]

**Summary:**
- Original length = 1.75 feet
- Original width = 0.75 feet
- Original area = 1.3125 square feet
