We are given that the Perimeter of screen in library is 14 feet

So,

Width of screen in library = 3 feet

The rectangular projection screen in the school auditorium is 5 times as long as the rectangular screen in the library.

So, Length of screen in auditorium =

The rectangular projection screen in the school auditorium is 5 times as wide as the rectangular screen in the library.

So, Width of screen in auditorium  =

Perimeter of the screen in the auditorium = 2(l+b)=2(20+15)= 70
