Answer:

area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375
The number of ways they can be seated in a row if both families want to sit together is 2 ways
Given that two families with four people in each family go to a movie theater, in order to determine the number of ways they can be seated in a row if both families want to sit together
We will use the permutation rule since it is about the arrangement.
We will take 4 people as 1 group and the other 4 people as another group.
If the groups are to sit together, the number of ways this can be done is 2!
2! = 2 * 1
2! = 2ways
This shows that the number of ways they can be seated in a row if both families want to sit together is 2 ways
