Answer:
The width of the flag is 70 ft.
Step-by-step explanation:
The shape of a flag is mostly rectangular.
The perimeter of a rectangle is,
[tex]Perimeter =2(l+w)[/tex]
Given:
Perimeter of flag = 460 ft.
Width = w
Length (l) = 90 + w
Determine the value of width as follows:
[tex]460=2(90+w+w)\\\frac{460}{2} =90+2w\\230-90=2w\\w=\frac{140}{2}\\ =70[/tex]
Thus, the width of the flag is 70 ft.
