## Task 2

A class estimates the length of a path on the schoolyard to be $28 \mathrm{~m}$. Two boys measure this path. They lay a measuring tape of $20 \mathrm{~m}$ length once and then measure another $12 \mathrm{~m}$.

By how many meters did the students overestimate?
$20+12-28=4$. The students are off by $4 \mathrm{~m}$.
