# The sides of a triangle are in the ratio 4 : 5 : 6. What is the length of each side if the perimeter is 45 cm?

$12 c m$
$15 c m$
$18 c m$

#### Explanation:

suppose the length of the sides are,

$4 x , 5 x , 6 x$

so,
$4 x + 5 x + 6 x = 45$

$\mathmr{and} , 15 x = 45$

$\mathmr{and} , x = 3$

so, the sides are,

$4 \times 3 = 12 c m$
$5 \times 3 = 15 c m$
$6 \times 3 = 18 c m$
