Step-by-step explanation:
We need to find total area of the two rooms (hexagon and nonagon) and then multiply that by 4.5 to get total cost.
Area of Hexagon =
Where a is the side length (which is 50)
Hence,
Area of Hexagon =
Also, area of Nonagon is given by
Where s is the length of the side
Hence,
Area of Nonagon =
Total floor area = 6495.2 + 15,454.5 = 21,949.7
Hence,
Total Cost = 21,949.7 * 4.5 = 98,773.65
