The lengths of the three sides of the triangle are 30 cm, 24 cm and 18 cm respectively. The length of the altitude of the triangle corresponding to the smallest side is-

It is given in the question that,

Sides of the triangle = 30 cm, 24 cm and 18 cm

Let h be the altitude of the triangle

∴ Semi-perimeter =

=

= 36 cm

Now, Area of triangle =

=

=

= 216 cm^{2}

Also, Area =

216 =

216 = 9 × h

h =

= 24 cm

Hence, option (a) is correct
