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.
Before he reaches a black belt there are many different colors such as yellow, blue, green, etc. When I started my karate training in early 60âs there were only two colors before black. They were white and brown. If I remember correctly I started from Mu-kyu (no kyu) and with the first exam I became 6th kyu.
Choose a color for your belt. Wear a black belt with every black suit or dark colored pant. Match a brown belt to khaki or other variety of brown. Use your style judgment for other colors like white, navy blue, or greens to ensure that your belt complements your outfit rather than contrasts it.
