Yes, you are correct! To determine the number of significant figures in the area of the rectangular room, you need to consider the least precise measurement given. In this case, the least precise measurement is 17.16 m, which has four significant figures. Therefore, the answer should have four significant figures as well.
Out of the given options, "343.2 m2" is the only one with four significant figures, so it represents the room's area with the correct number of significant figures. Well done!
