Mathematics

12 feet

Step-by-step explanation:

On a scale drawing of a boat, 15 feet are represented by 10 inches.

This means $15\,\,feet=10\,\,inches$

$1\,\,inch=\frac{15}{10}\,\,feet=\frac{3}{2}\,\,feet$

Now, find the length of the boat if the drawing was 8 inches long.

Length of the boat = $8(\frac{3}{2})=12\,\,feets$

So, length of the boat is 12 feets if the drawing was 8 inches long.
