The 13 stripes alternate red and white: 7 red and 6 white.
Each of 13 stripes is (39 in. / 13) = 3 in. wide.
4 of the 7 red stripes are 39 in. long. The other 3 are 65 in. long.

The total area (l*w) of the flag is (65 in.)*(39 in.)=2535 sq. in.

The red stripes make up an area (l*w) that is:
4*(area of short stripes) + 3*(area of long stripes)
Red area is 4*(39*3) + 3*(65*3) = 1053 sq in.

The fraction of the flag that is red is:
1053 sq. in. / 2535 sq. in.
