Out of all the measurements used in the calculation, find the one with the least number of significant digits. This will be the limiting factor of how many significant digits the answer should have.
To determine the number of significant figures in the answer to the calculation 65.25 m x 37.4 m, we look at the significant figures of each number. The number 65.25 m has four significant figures, while 37.4 m has three significant figures. The result should be reported with the least number of significant figures, which is three in this case. Therefore, the answer will have three significant figures.

The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.

There should be 3.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
It should have three.
To determine the number of significant figures in the answer to the calculation 65.25 m x 37.4 m, we look at the significant figures of each number. The number 65.25 m has four significant figures, while 37.4 m has three significant figures. The result should be reported with the least number of significant figures, which is three in this case. Therefore, the answer will have three significant figures.
When performing multiplication or division, the result should be rounded to the same number of significant figures as the measurement with the fewest significant figures involved in the calculation. For example, if you multiply a number with three significant figures by a number with five significant figures, the final answer should be rounded to three significant figures. This rule ensures that the precision of the answer reflects the least precise measurement used in the calculation.
That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.
