1 Square footage: To measure commercial square footage, multiply the length of the room in feet by its width. 2  For example, a room that is 12 feet (3.7 m) long by 12 feet (3.7 m) wide is 144 square feet (13.4 square m).3  12x12=144.4  Unusual shapes: Take care when measuring irregularly shaped sections of a room. If the length of the space with the diagonal wall was 10 feet (3.0 m) and its width was 8 feet (2.4 m), the square footage of the area would be 40 feet (3.7 square m). 2  That is because the wall cuts the total square footage, which would have been 80 if the room had no wall intersecting it, in half. 3  10x8=80 and 80/2=40.
Thus karate followed the rule change and the highest rank in Shotokan is 10th dan now. In some styles of karate a higher degree wears a different color belt. A practitioner of 6th, 7th or 8th dan would wear a red and white belt (photo above). For 9th and 10th dan a full red belt may be worn. These belts are also the imitation from the judo policy.
Meanings Of The Belt Colors by. Grand Master James S. Benko. The color of the belts used is by no means merely some random selection of colors to distinguish the different ranks. Each belt color has a meaning symbolizing advancement and increased awareness. The color belt system is not just a representation of rank advancement, it is also is an acknowledgement of individual personal growth. Such advancement signifies not only growth within the dojang (training hall), but that of positive character and growth outside of the dojang.
