Question

The height of a certain banner is equal to one third of its length. If the banner is 5 ft tall, write the equation that can be used to find the banners lenghth,L, in feet.

Answer 1

`L=3h`

Explanation:

Let height of a banner be
`h`, then we know that this is
`(1)/(3)` of the length
`L` of the banner; so we have

`h=(1)/(3) L` .

Now we can rearrange this equation to solve for the length of the banner given it's height:

`L=3h`

So there we have it!

If the banner is 5 ft tall, then it's length will be:

`L=3*5=15ft`
