Answer:

Step-by-step explanation:

Given

L  = 2ab + 2bc + 2ac ( subtract 2ab from both sides )

L - 2ab = 2bc + 2ac ← factor out c from each term on the right side

L - 2ab = c(2b + 2a) ← divide both sides by (2b + 2a)

[tex]\frac{L-2ab}{2b+2a}[/tex] = c

Then

c = [tex]\frac{108-2(4)(6)}{2(6)+2(4)}[/tex]

  = [tex]\frac{108-48}{12+8}[/tex]

  =[tex]\frac{60}{20}[/tex]

 = 3
