{person['name']} is $5$ft $\\var{inches}$ inches tall.

\n

a)

\n

To find {person['name']}'s height into cm, we first convert it into inches. 

\n

We can convert feet into inches by multiplying by $12$. So $5$ feet is

\n

\\[ 5\\times12=60 \\text{ inches.}\\]

\n

Therefore $5$ft $\\var{inches}$ inches is 

\n

\\[
60+\\var{inches} = \\var{60+inches}\\text{ inches.}
\\]

\n

We can now convert this to cm by multiplying by $2.54$.

\n

\\[\\var{60+inches}\\times2.54=\\var{cm}\\text{ cm, rounded to the nearest integer.}\\]

\n

b)

\n

To convert centimetres into metres, we divide by $100$:

\n

\\[\\var{cm}\\div100=\\var{dpformat(cm/100,2)} \\text{ metres.}\\]

\n

Therefore, {person['name']} is $\\var{dpformat(cm/100,2)}$ metres tall.
