Perimeter of an isosceles triangle is 50 cm. If one of the two equal sides is 18 cm, find the third side.
उत्तर
Let ∆ABC be the given isosceles triangle, where AB = CA = 18 cm.
Perimeter of the ∆ABC = 50 cm
⇒ AB + BC + CA = 50 cm
⇒ 18 cm + BC + 18
⇒ 36 cm + BC = 50 cm
⇒ BC = 50 cm – 36 cm
⇒ BC = 14 cm
