Question

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

Answer 1

5x+12x+13x=300
30x=300
X=300÷30
X=10
Now,
5x=5×10=50
12x=12×10=120
13x=13×10=130
Now,130,120,50 are the sides of the triangle.
