Apartment area

Anton wanted to measure the area of the apartment. But he bought a meter only 1.5m long. Later he recalled that he had two meters long at 4.5m and 18m at home. How many times are home gauges longer than the meter he bought?

Correct result:

n₁ =  3
n₂ =  12

Solution:

$$\begin{gathered} a=1.5\text{ m } \\ b=4.5\text{ m } \\ c=18\text{ m } \\ {n}_1=b\mathrm{/}a=4.5\mathrm{/}1.5=3 \end{gathered}$$

$n_2=c\mathrm{/}a=18\mathrm{/}1.5=12$
