Area = Length * Width

Volume = Length * Width * Height

As you can likely already see, we have a problem. The question asks for “area” but gives a measurement for Length, Width, and height.

So the best I can do is give the answer of the total “Surface area” of the room.

Floor = 12m * 7m = 84m^2

Roof = 12m * 7m = 84m^2

Front/Back walls (x2) = 7m * 4m * 2 = 56m^2

Side walls (x2) = 12m * 4m * 2 = 96m^2

Total surface area

= 84m^2 + 84m^2 + 56m^2 + 96m^2

= 320 m^2

hope this answer help you thanks for asking me this question..
