Question

sides of triangle are 5cm 12cm and 13cm find its area and height on Base 12cm...........
plzz solve it completely

Answer 1

Let a cm be the height of the triangle,

Using Pythagoras Theorem,
(12)^2 + a^2 = 13^2
a= 5
The height = 5 cm
(This triangle is a right-angled triangle.)

The Area
=(12*5) / 2 cm^2
=30 cm^2
