Question

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 440 feet. Determine the​ flag's length and width if the length is 60 feet greater than the width?

Answer 1

I found `80`ft and `140`ft.

Explanation:

As we consider a rectangle we can call `l` the length and `w` the width so that the perimeter will be:
`2l+2w=440`
And also:
`l=w+60`
That substituted into the perimeter gives:
`2(w+60)+2w=440`
`4w+120=440`
`4w=320`
`w=320/4=80`ft
And so:
`l=80+60=140`ft
