2 patratele = 1 cm
6 patratele = 2 patratele + 2 patretele + 2 patratele → suma a 3 termeni egali
↓ ↓ ↓
6 patratele = 1 cm + 1 cm + 1 cm = 3 cm
10 patratele = 2 patratele + 2 patratele + 2 patratele + 2 patratele + 2 patratele
→ suma de 5 termeni egali
10 patratele = 1 cm + 1 cm + 1 cm + 1 cm + 1 cm = 5 cm
6 patratele = 2 patratele + 2 patretele + 2 patratele → suma a 3 termeni egali

6 patratele = 1 cm + 1 cm + 1 cm = 3 cm
10 patratele = 2 patratele + 2 patratele + 2 patratele + 2 patratele + 2 patratele
→ suma de 5 termeni egali
10 patratele = 1 cm + 1 cm + 1 cm + 1 cm + 1 cm = 5 cm
