Let the length of the shorter ship = +x+
+x+%2B+%28+x+%2B+7+%29+=+2647+
+2x+%2B+7+=+2647+
+2x+=+2640+
+x+=+1320+
and
+x+%2B+7+=+1327+
-------------------
The lengths of the ships are
1320 ft and 1327 ft
------------------------------
Convert +100+ yds to feet
+100%2A3+=+300+ ft
+1327%2F300+=+4.42333++ football fields
