Step-by-step explanation:

This is a ratio problem

Step one:

Given the ratio of length:width is <em> "3 space colon space square root of 3"</em>

mathematically it is expressed as

length:width 3:√3 or 3/√3

Step two:

3:√3 or 3/√3

if the built TV has a width of 6ft let the length be x

x√3=18

x=18/√3ft

therefore the length will be 18/√3ft
