Answer:
28 ft^2
Step-by-step explanation:
The room is in the shape of a square. That means the base of the room (width and length) will have the same dimensions.
Length x Width = 49 ft^2
Length = Width
Length^2 = 49 ft^2
Length = 7 feet
Width is also 7 feet
The height of the room is 4 feet, plenty for non-humans. One wall area would be (7 ft)*(4 ft) = 28 ft^2
