Answer:
Two significant figures
Step-by-step explanation:
In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.
2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)
There are three significant figures in 2.05, but only two in 32.
You must round to <em>two</em> significant figures and report the answer as 66 cm².
65.600 000 00 cm² ⟶ 66 cm²
