Question

ΔABC is right angled at A. AD is perpendicular to BC. If AB = 5 cm, BC = 13 cm and AC = 12 cm

Answer 1

: Given that triangle ABC right angled at A. Base = AB = 5cm, Height = AC = 12 cm Therefore, Area of the triangle = Base x Height. Area = AB x AC = 5 cm x 12 cm⇒ Area = 60 cm2. Now, consider BC = Base, Height = AD. Area = Base x Height.⇒ 60 cm2 = 13cm x AD AD = 60 / 13 ⇒ AD = 4.615 cm
