Step1: Let the middle side length
Let the middle side length be \(x\) meters. Then the other two side lengths are \((x - 2)\) meters and \((x+2)\) meters.
Step2: Use the perimeter formula
The perimeter of a triangle \(P=a + b + c\). Here, \(P=(x - 2)+x+(x + 2)\). Simplify the expression: \((x - 2)+x+(x + 2)=x-2+x+x + 2=3x\).
Step3: Solve for \(x\)
Since the perimeter \(P = 93\) meters, and \(P = 3x\), we have the equation \(3x=93\). Divide both sides by 3: \(x=\frac{93}{3}=31\).
