GIVEN:
total length of the banner = 30 ft.
perimeter of the banner = 96 ft.
total width of the rectangle = ?
Let,
the perimeter be "p"
the length be "L"
the width be "w"
We know,
Perimeter (P) of a rectangle = 2 (L + w) 
Substituting the values of P, L and w , we get,
                                      96  = 2 (30 + w)  
                                  96 / 2 = 30 + w
                                       48 = 30 + w
                                48 - 30 = w
                                       18 = w

So, the width of the rectangular banner is 18 ft.
