A RIGHT ANGLED TRIANGLE ABC IS GIVEN,WHERE AB IS 5CM,AC IS 12CM,BC IS 13CM,AD IS AN ALTITUDE FROM A TO BC,FIND THE AREA OF THE TRIANGLE AND FIND AD ALSO.
area = (1/2)base x height
= (1/2)(5)(12) = 30
We could also consider BC as the base, then AD becomes the height
so (1/2)(13)(AD) = 30
AD = 2(30)/13
your ans will may be wrong because height and base could not accept on those questions database
