7th Grade Math Formula Sheet

Original length = feet

Original width = feet

Original area = square feet

Answer 1

To determine the original dimensions and area of the rectangle, utilize the information provided:

1. **Calculate the original length**:
- Scale drawing length = 12 units
- Each unit represents 3.5 feet.
- Original length = Scale drawing length × Length per unit
- Original length = 12 units × 3.5 feet/unit = 42 feet

2. **Calculate the original width**:
- Scale drawing width = 4 units
- Each unit represents 3.5 feet.
- Original width = Scale drawing width × Width per unit
- Original width = 4 units × 3.5 feet/unit = 14 feet

3. **Calculate the original area**:
- Area = Length × Width
- Area = 42 feet × 14 feet = 588 square feet

So the answers are:

- **Original length = 42 feet**
- **Original width = 14 feet**
- **Original area = 588 square feet**
