Question

Triangle ABC is a right angled triangle at A.AD is perpendicular to BC.If AB=5cm and AC=12cm,then find the length of AD.

Answer 1

Answer:

Step-by-step explanation:

Sol:

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
