## Task 1

Draw a line segment that is $4 \mathrm{~cm}$ long, and below it, draw a second one that is $3 \mathrm{~cm}$ longer. Now add a third line segment that is $5 \mathrm{~times}$ as long as the first! How long are the second and the third line segments?
2. Line: $4+3=7$, i.e. $7 \mathrm{~cm}$; 3. Line: $5 \cdot 4=20$, i.e. $20 \mathrm{~cm}$
