Teng tomonli uchburchakning tomoni (3x − 1) ga, kvadratning tomoni esa (4x − 6) ga teng. Agar ularning perimetrlari teng bo'lsa, x ning qiymatini toping.

📝 Batafsil tushuntirish

Uchburchak perimetri: 3 × (3x − 1) = 9x − 3. Kvadrat perimetri: 4 × (4x − 6) = 16x − 24. Ularning perimetrlarini tenglashtiramiz: 9x − 3 = 16x − 24 ⇒ 21 = 7x ⇒ x = 3.
