- Part A
What is the area, in square inches, of the actual flag?
If the scale is 1:18 it means that the drawing is 18 times less than the real flag, in this the dimensions are:
2inch and 1inch
A = 2 * 1 = 2inch²
A = (2 * 18) * (1 * 18) = 648in² is the actual area
- Part b
What should be the height, in inches, of the letter "L" on the scale drawing?
If an L is drawn on the 9-inch-high royal flag, the drawing will measure
9 ÷ 18 = 0.5
0.5 inch on the drawing
