you calculate the area of a 150 m x 100.0 m room. How many significance figures should your answer include ?

a) 1
b) 2
c) 3
d) 4

one of the dimenhsions has two significant figures, the other has four. The answer must have two signficant figures.

To calculate the area of a rectangle, you multiply its length by its width. In this case, the given dimensions are 150 m and 100.0 m for the length and width, respectively.

To determine the number of significant figures in the answer, you should consider the measurement with the fewest significant figures.

In this case, the width is given as 100.0 m, which has four significant figures. Therefore, the final answer should be expressed with the same number of significant figures to maintain accuracy and precision.

So, the correct answer is:

d) 4
