True,
Good luck! I hope I helped!
It's too blurry to read. If you tell me what it says, I'll try to give you an answer.
M is the centroid and the centroid divide the line in 1:2 ratio . So M divide BQ in 1:2 ratio and the total length of BQ is 18.
Therefore BM is one third of 18 . ANd one third of 18=6
So BM =6 and MQ=12 .
area of the ceiling = 55 x 55 = 3025 square feet
3025/275 = 11 cans
Negative 72.75 is your product. It is very simple once you understand it.
