A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 500 feet. Determine the​ flag's length and width if the length is 130 feet greater than the width.

What is the​ flag's width?

1 answer

2 L + 2 w = 500
but L = (130 + w)
(260 + 2w) + 2w = 500
4 w = 240
w = 60
L = 190
================
check
190 - 60 = 130
2 w + 2 L = 120 + 380 = 500, whew!
