Question: 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?
3
What are the actual length and width of the trampoline?
Actual length = ft
Actual width = ? ft
An error has occurred. Please enter a number.
l = 4 in.
w = 2 in.
1 in. : 3 ft
1. **State the problem:** We have a scale drawing of a trampoline with length $l = 4$ inches and width $w = 2$ inches. The scale is $1$ inch : $3$ feet. We want to find the actual length and width of the trampoline.
2. **Identify the scale factor:** The scale tells us that each inch in the drawing corresponds to $3$ feet in reality. So, the number to multiply each length in the scale drawing by is $3$.
3. **Calculate the actual length:**
$$\text{Actual length} = 4 \text{ in.} \times 3 \frac{\text{ft}}{\text{in.}} = 12 \text{ ft}$$
4. **Calculate the actual width:**
$$\text{Actual width} = 2 \text{ in.} \times 3 \frac{\text{ft}}{\text{in.}} = 6 \text{ ft}$$
5. **Final answer:**
- Actual length = $12$ ft
- Actual width = $6$ ft
This means the trampoline is $12$ feet long and $6$ feet wide in reality.
