Question

The perimeter of a triangular field is 300 cm and its sides are in the ratio 5:12:13. Find the length of the perpendicular from the opposite vertex to the side whose length is 130 cm.​

Answer 1

Step-by-step explanation:

the lengths of the sides are 50,120,130

s=150

by using herons formula

√s(s-a)(s-b)(s-c)

√150(150-50)(150-130)(150-120)

√150*100*20*30

√30*5*20*5*20*30

30*5*20

area=3000cm^2

1/2*130*h=3000

65h=3000

h=3000/65

h=46.15
