Question

triangle ABC is right angled at a. AD is perpendicular to BC. If AB=5 BC=13 AC=12.Find area of triangle ABC. find the length of AD​

Answer 1

In Triangle ABC

AC is the base of 12cm

and AB is the height of 5cm

Now, ar. of triangle=1/2×base(AC)×height(AB)

=1/2×12×5

=30

Now,let AD be the height

Therefore,ar. of triangle=1/2×12×AD

30=6×AD

AB=30/6

AD=5cm

Answer 2

therefore the length of AD is 5
