Short answer: 36.
This is a combination/permutation problem.
To put it simple, a die has 6 sides, there are 7 days but 1 is already determined (12 laps).
So if we multiple the options (sides on a die) × the number of days (6) we get:
6 × 6 = 36 possible outcomes.
To show this we can get
12, 13, 14, 15, 16, 17, 18
12, 13, 14, 15, 16, 17, 19
12, 13, 14, 15, 16, 17, 20
... all the way to
12, 18, 24, 30, 36, 42, 48
Answer:
She will need 4 square and 8 triangular pieces.
Step-by-step explanation:
For every 6 pieces of cloth, 2 are squares.
So, for 12 pieces of cloth, the no. of square pieces would be,

As the remaining pieces will be triangles, so the no. of triangular pieces will be, equal to,
(12 - 4) = 8
