A triangle has sides 5cm, 12cm, 13cm. The length of the perpendicular from the opposite vertex to the side whose length is 13cm is?
It is clear that the triangle is a right angled triangle.
Let AB=12 cm BC=5 cm and AC=13 cm
Now a perpendicular is drawn from A to AC.
Putting the respective values of the sides we get,
You can also apply the heron's formula to get the answer to the question.
The given side of triangle are
Now, using Heron's formula, the area
