A. 32mm^2
B. 33mm^2
C. 32.5mm^2
D. 32.51 mm^2

Answer 1

B. 33 mm²

Step-by-step explanation:

The language "product" means that we must multiply the numbers given to get our answer.

5.4 mm × 6.02 mm = 33 mm²

The significant figures rule for multiplication is that we must us the amount of significant figures in the number with the least significant figures, in this question this is 2 significant digits from 5.4 mm.
