Mathematics

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

Where x is a multiple.

Perimeter of triangle = 3x + 4x + 5x

$\bf \rightarrow \: 96 \: = \: 12x$

$\bf \rightarrow \: \frac{96}{12} \: = \: x \\$

$\bf \rightarrow \: \cancel\frac{96}{12} \: ^{8} \: = \: x \\$

$\bf \rightarrow \: x \: = \: 8$

Required sides are :

$\bf \implies \: 3x \: = \: 3 \: \times \: 8 \: = 24$

$\bf \implies \: 4x \: = \: 4 \: \times \: 8 \: = 32$

$\bf \implies \: 5x \: = \: 5 \: \times \: 8 \: = 40$

Hence , the sides of the triangle are 24 , 32 and 40.

the lengths of the sides of a triangle are in as ratio 3:4:5., find the lengths of the sides of this
