This graph shows the directly proportional relationship between lengths in meters (metric) and lengths in feet (imperial).

Use the graph to estimate how many feet there are in four meters.

This graph shows the directly proportional relationship between lengths in meters (metric) and lengths in feet (imperial).

Given that $1 \mathrm{m}=3.28$ feet and one foot$=0.305 \mathrm{m}$, calculate how many feet there are in $4$ meters.

This graph shows the directly proportional relationship between lengths in meters (metric) and lengths in feet (imperial).

Which is longer:

four meters or $12$feet
