Question

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?

Answer 1

`12cm`
`15cm`
`18cm`

Explanation:

suppose the length of the sides are,

`4x,5x,6x`

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

`or,15x=45`

`or,x=3`

so, the sides are,

`4xx3=12cm`
`5xx3=15cm`
`6xx3=18cm`
