To answer this, you will start with the scale of 1 in:4 ft. I suggest writing in fraction form -see picture.

Make this equivalent to x:15 ft (also in fraction form).

To set this up as an equation use cross products (multiply the diagonal sides)-see picture.

Then solve the equation by dividing both sides by 4.

Her rotors are 3.75 inches in her drawing.
