Question

the side of the triangle are 5cm,12cm and 13cm find the length of perpendicular from the opposite vertex to the side whose length is 13cm

Answer 1

Area Of Triangle = Square Root Of (S(S-A)(S-B)(S-C))

Now S = 5+12+13/2 = 15

Area = Square Root Of (15*10*3*2)

Area = Square Root Of (900)


Area = 30

Now Area Of Triangle = 1/2*Base*Height

Base = 13

1/2*13*Height = 30

13*Height = 60

Height = 60/13 = 4.61 cm
