Calculate the area, with the appropriate number of significant figures, of a rectangular room that is 14.10 m wide by 15.0 m long.
If I multiply the two values and round to the nearest whole number, I get 212 m^2. Is this right?

yes
it is 212 m^2 i just took the quiz

It’s 212
To calculate the area of a rectangle, you multiply its length by its width. In this case, the length is 15.0 m and the width is 14.10 m.
To multiply these values, you can make use of a calculator or perform the calculation by hand:
15.0 m * 14.10 m = 211.5 m^2
Now, when rounding to the appropriate number of significant figures, we need to look at the least precise measurement given. In this case, the 14.10 m has three significant figures, while the 15.0 m has just three.
Since 15.0 is the least precise, we need to round the final answer to three significant figures. Therefore, the correct answer rounded to the appropriate number of significant figures is:
Area = 211.5 m^2 (rounded to three significant figures)
