Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
That would be -2 1/2 , 3 1/2

Answer:
49 cm²
Step-by-step explanation:
Formula for area:
a = l (length) x w (width)
if its 7 cm on each side, then the length and width will be 7
7*7 = 49 cm²
There are many ways to do this.
One way could be 0.25x+7.00=27
