(REMEMBER: Final label is ft.)
Hallway = (1/2 in. (width) x (2 in. (length) + 3 in. (length)) x 6 ft. (actual size)
Hallway = (1/2 in. (width) x 5 in. (length)) x 6 ft. (actual size)
Hallway = 5/2 in. (area) x 6 ft. (actual size)
Hallway = 15 ft^2 (final answer)
Kitchen = (3 in. (width) x 3 in. (length)) x 6 ft. (actual size)
Kitchen = 9 in. (area) x 6 ft. (actual size)
Kitchen = 54 ft^2 (final answer)
