Answer:
the width is 470 ft and the length is 730 ft.
Explanation:
Perimeter of a flag is 2l+2w
Let w = width
Let l = w+260
2(w+260)+2w=2,400
2w+520+2w=2400
4w+520=2400
4w=1880
w=470
So, the length would be 470+260, or 730
Therefore, the width is 470 ft and the length is 730 ft.
I hope this helped and have a good rest of your day!
