Answer:
1234567890
Step-by-step explanation:
Each of the digits is divisible by their individual index in the number. Adding a 0 at the ends allows for the number to be divisible by 10 and completes the 10 digit requirement.
Must be 16 and 21 because we can see
30 and 70 has 10 as factor
24 and 44 has 2 as factor
12 and 30 has 2 as factor and all those factors are greater than one
A square has all the sides being equal.
Since the top can fit 3 color tiles, then the side must fit the same number of tiles.
Therefore, 3 roles and 3 columns of tiles will be required.
The number of tiles required will calculated similar to area of a square. That is,
Number of tiles = 3*3 = 9 tiles.
Add all of the sides together
9+24+9+15+15
33+24+15
57+15
= 72 feet
Answer is 72 feet - D
