Respuesta :

[tex] \frac{35}{100} = \frac{51.8}{x} [/tex]

Cross multiply

[tex] 35x=5180 [/tex]

divide 35 from each side

x=148

The total length is 148 feet. 
t(0.35)=51.8

where t is the total length of the screen
times 0.35 which is 35% in decimal form
51.8 is 35% of the screen

t(0.35)=51.8
   ------  -------
   0.35   0.35
t=148 

The total length of the screen is 148 ft.
