Answer: 380 ft and 780 ft

Explanation:

We can assume that the flag is a rectangle. If the width of the flag is w, then the length is w + 400.

The formula for the perimeter of a rectangle is
2(l+w). Let's plug in the values we know.


P=2(l+w)\\2320=2(w+400+w)\\1160=2w+400\\760=2w\\w=380

We know that the length is 400 more than the width, so let's find the length.


l=w+400\\l=380+400=780

Hence, the flag's width is 380 ft and the length is 780 ft.
