Bradford · Answer 1

we are asked to multiply 5.4 mm by 6.02 mm

5.4 mm has 2 significant figures

6.02 mm has 3 significant figures

When multiplying these 2 numbers the answer should have the least number of significant figures

From the 2 numbers the least number of significant figures is 2, therefore answer should be rounded off to 2 significant numbers

5.4 x 6.02 = 32.5 rounded off is 33

Answer is b. 33 m^2
