Question: User: Jazlyn owns an indoor trampoline park. The scale drawing shows a new trampoline she wants to purchase for her facility. The scale is shown in the drawing.
What number can you multiply each length in the scale drawing by to find the actual length?
l = 4 in.
w = 2 in.
1 in. : 3 ft
1. **State the problem:**
We have a scale drawing of a trampoline with lengths given in inches, and a scale that relates inches in the drawing to feet in real life.
2. **Identify the scale:**
The scale is given as $$1 \text{ in.} : 3 \text{ ft}$$ which means every 1 inch in the drawing corresponds to 3 feet in actual length.
3. **Find the multiplier:**
To find the actual length from the drawing length, multiply the drawing length by 3.
4. **Apply the multiplier:**
- For length $$l = 4 \text{ in.}$$ actual length is $$4 \times 3 = 12 \text{ ft}$$.
- For width $$w = 2 \text{ in.}$$ actual length is $$2 \times 3 = 6 \text{ ft}$$.
5. **Answer:**
The number you multiply each length in the scale drawing by to find the actual length is **3**.
This means the scale factor is $$\boxed{3}$$.
