The equal sides of an isosceles triangle is 8cm and the other side is 10 cm. What will be the area of this triangle in sq. cm? Correct Answer 31.22
Perimeter = 8 + 8 + 10 = 26 cm Semi – perimeter = 26 / 2 = 13 cm Area of triangle = √s(s – a) (s – b) (s – c) ➩ √13 (13 – 8) (13 – 8) (13 – 10) ➩ √13 (5) (5) (3) ➩ √975 ➩ 31.22 cm2
