Answer:
Step-by-step explanation:
Using the cosine theorem:



The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
The area of the room must equal the sum of the areas of the tiles...
20*30=n(2*3)
600=6n
n=100
So 100 tiles are needed.
The base is the greatest surface area
