1. **State the problem:** We have a scale drawing of a flag with dimensions 1 inch by 2 inches. The scale factor from the drawing to the actual flag is 1:18. 2. **Find the area of the actual flag:** - The area of the drawing is $1 \times 2 = 2$ square inches. - The scale factor for lengths is 1:18, so the scale factor for areas is the square of 18, which is $18^2 = 324$. - Therefore, the area of the actual flag is $2 \times 324 = 648$ square inches. 3. **Find the height of the letter "L" on the scale drawing:** - The actual height of the letter "L" is 9 inches. - Using the scale factor 1:18, the height on the drawing is $\frac{9}{18} = \cancel{\frac{9}{\cancel{18}}} \frac{1}{2} = 0.5$ inches. **Final answers:** - (a) The area of the actual flag is **648** square inches. - (b) The height of the letter "L" on the scale drawing is **0.5** inches.
