Answer:

  12

Step-by-step explanation:

When n teams play each other once, the total number of games is n(n-1)/2. Since each team played every other one 3 times, the relationship between number of teams (n) and number of games is ...

  3(n(n-1)/2) = 198

  n(n-1) = 132 = 12·11 . . . . . . multiply by 2/3 and factor

  n = 12 . . . . . . n = -11 is also an extraneous solution to this quadratic equation

12 teams participated in this championship.

43 5/12 x 11 Please help
zzz [600]
The perimeter is the sum of side lengths. Opposite sides of a rectangle are the same length, so the perimeter is
  P = 11 +43 5/12 +11 +43 5/12
    = 2(11 +43 5/12)
    = 2(54 5/12)
  P = 108 5/6 . . . . feet

The area is the product of length and width. It doesn't matter which of the given dimensions you consider length or width, since you multiply them either way.
  A = 11 * 43 5/12
    = 473 +55/12
  A = 477 7/12 . . . . square feet
