Question

What is the actual length from the airplane

Scale drawing: length: 12 in. Height: 3 in.
Actual airplane: length:___ ft height: 9ft

The scale factor is 3

Answer 1

To find the actual length of the airplane based on the scale drawing and the scale factor, we can use the information provided.

1. **Scale drawing dimensions:**
- Length: 12 inches
- Height: 3 inches

2. **Scale factor:** 3

To find the actual length based on the scale factor, you can multiply the length in the scale drawing by the scale factor:

\[
\text{Actual Length} = \text{Scale Length} \times \text{Scale Factor}
\]

For the length:

\[
\text{Actual Length} = 12 \text{ in.} \times 3 = 36 \text{ in.}
\]

Convert inches to feet (since there are 12 inches in a foot):

\[
\text{Actual Length in feet} = \frac{36 \text{ in.}}{12} = 3 \text{ ft}
\]

So, the actual length of the airplane is **3 ft**.

The actual height is already provided as **9 ft**.

In summary, the length of the actual airplane is **3 ft** and the height is **9 ft**.
