# 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?

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:
$2 l + 2 w = 440$
And also:
$l = w + 60$
That substituted into the perimeter gives:
$2 \left(w + 60\right) + 2 w = 440$
$4 w + 120 = 440$
$4 w = 320$
$w = \frac{320}{4} = 80$ft
And so:
$l = 80 + 60 = 140$ft
