Answer:
The area Marco and his friends will need to paint is
[tex]782ft^2[/tex]Explanation:
Given that:
The floor of the room is 23.5 ft by 22.5 ft
The walls of the room are h = 8.5 ft tall
The length and width of the floor will be the same as that of the wall, so, the area Marco and his friends will need to paint is:
[tex]\begin{gathered} 2(8.5)(23.5+22.5) \\ =17(46) \\ =782ft^2 \end{gathered}[/tex]
