draw B'C' =13cm
then divides B'C in the ratio of 3:4:5
B'B : B'C: C'C = (by similarity of triangle)
Now construct = AB = B'B
construct = AC = C'C
Hence AB: BC:AC=3:4:5
Hence triangle ABC is a required triangle
Hence AB =13/4cm BC=13/3cm or AC= 65/12cm
then divided the result is 3:4:5
then divides B'C in the ratio of 3:4:5
B'B : B'C: C'C = (by similarity of triangle)
Now construct = AB = B'B
construct = AC = C'C
Hence AB: BC:AC=3:4:5
Hence triangle ABC is a required triangle
Hence AB =13/4cm BC=13/3cm or AC= 65/12cm
then divided the result is 3:4:5
