The rectangular projection screen in the school auditorium is 5 times as long and 5 times as wide as the rectangular screen in the library. the screen in the library is 4 feet long with a perimeter of 14 feet. what is the perimeter of the screen in the auditorium?

Library: length 4, width 3 = 4(2)+3(2)=14

Take the length and width and multiply them by 5.

4*5=20 and 3*5=15

20(2)+15(2)= 70

The perimeter of the auditorium screen is 70.
