Question

triangle has sides 6 cm 12 cm and 13 cm find the length of perpendicular from the opposite vertex to the side whose length is 13 cm

Answer 1

the given triangle is right angles triangle
so the area of triangle is
1/2*6*12
=36
but if we draw IA perpendicular to side of length 13
then area of triangle is
=1/2*13*perpendicular distance
but area = 36
therefore,
1/2*13*perpendicular distance = 36
perpendicular distance = 4 cm

Answer 2

Answer:

the given triangle is right angles triangle

so the area of triangle is

1/2*6*12

=36

but if we draw IA perpendicular to side of length 13

then area of triangle is

=1/2*13*perpendicular distance

but area = 36

therefore,

1/2*13*perpendicular distance = 36

perpendicular distance = 4 cm
