One of the equal sides of an isosceles triangle is 13 cm and its perimeter is 50 cm. Find the area of the triangle.

Given: One of the equal sides of an isosceles triangle = 13 cm Perimeter of the triangle = 50 cm Let `a` be the length of the third side of the triangle. ∵ Perimeter of triangle = sum of sides ⇒ 13 \+ 13 \+ a = 50 cm ⇒ 26 \+ a = 50 cm ⇒ a = 50 \- 26 cm ⇒ a = 24 cm Let a = 13 m, b = 13 m and c = 24 m. ∵ Area of triangle = = cm 2 = cm 2 = cm 2 = 60 cm 2 Hence, the area of the triangle is 60 cm 2 .
