First, we can draw a picture to understand more easily what the exercise asks of us:
Then, if they tell us that the perimeter is 179 feet, we have:
[tex]x+2x+27+x=179[/tex]Because the perimeter is the sum of all the sides of a geometric figure. So that,
[tex]\begin{gathered} x+2x+27+x=179 \\ 4x+27=179 \\ 4x=179-27 \\ 4x=152 \\ x=\frac{152}{4} \\ x=38 \end{gathered}[/tex]Then the other sides measures
[tex]\begin{gathered} 2x=2\cdot38=76 \\ \text{An the third side:} \\ 27+x=27+38=65 \end{gathered}[/tex]Finally,
