Answer:
Yes
Explanation:
You want to know if a room with length in [7.5, 7.6] meters and width in [5.4, 5.5] meters can be used as a library requiring a minimum area of 40 square meters.
Area
The smallest area the room can have is the product of the shortest dimensions:
(7.5 m)(5.4 m) = 40.5 m²
The area of the room is at least 40.5 m², so can be used for the library (yes).
