Question

The perimeter of a triangle $ABC$ is $27cm$ and the ratio between the lengths of its sides is $2:3:4$ find the sides .

• A. $6,9,12$
• B. $3,6,9$
• C. $3,4,5$
• D. $None$

Answer 1

The correct option is A $6,9,12$

The perimeter of triangle $27cm$

The ratio of sides is $2:3:4$

The sides are given as

$\frac{2}{9}\times 27=6$

$\frac{3}{9}\times 27=9$

$\frac{4}{9}\times 27=12$

So the sides are $6,9,12$
