## Task 2

Petra estimates the length of the kindergarten garden to be $50 \mathrm{~m}$. Ivo and Mario measure this distance. They lay out a measuring tape of $20 \mathrm{~m}$ length twice and then measure another $12 \mathrm{~m}$.

By how many meters did Petra overestimate?
$2 \cdot 20+12=52 \mathrm{~m}$; Petra miscalculated by 2 meters.
