Question

1. perform the following operation: (26.9 cm)(5.0 m). 13 m² 130 m² 1300 m² 1.3 m²

Explanation:

Step1: Convert cm to m

Since 1 m = 100 cm, then 26.9 cm=$\frac{26.9}{100}$m = 0.269 m.

Step2: Multiply the two values

(0.269 m)×(5.0 m)=0.269×5.0 m² = 1.345 m².

Step3: Round to the correct number of significant - figures

The number 5.0 has 2 significant figures. Rounding 1.345 m² to 2 significant figures gives 1.3 m².

Answer:

1.3 m²
