Question

perimeter of a triangular field is 144 metre and its sides are in the ratio 3:4:5 .f Find the length of perpendicular from the opposite vertex to side whose length is 60 m

Answer 1

3x+4x + 5x=144m
12x=144m
x=144m/12
x = 12
first =3x = 36m
=46m
=60 m

Answer 2

Answer:

Let the sides of the triangle be 3x, 4x and 5x

∴ The perimeter of the triangular field = 144 m

⇒ 3x + 4x + 5x = 144

⇒ 12x = 144
