I'll attempt this later if nobody gets to it first

Answer 3

The area of region A is:
40*w = 480
Find the value of w.
Next, find the scale factor. It will be a ratio 3 in/ w as the ratio of corresponding sides.

Answer 4

For Part B use the scale factor and dimensions of the image to find the dimensions of the actual flag.
(3 + 2 + 3 + 1) = 9 in and (2 + 8) = 10 in
Divide 9/s and 10/s to find the required numbers. s- is the scale factor you will have found above.
