Question

find n. perimeter = 350 meters
80 m

Explanation:

Step1: Write the perimeter formula for rectangle

The perimeter formula for a rectangle is \(P = 2(l + w)\), where \(P\) is the perimeter, \(l\) is the length, and \(w\) is the width. Here \(P = 350\) meters and \(w=80\) meters, and \(l = n\). So, \(350=2(n + 80)\).

Step2: Divide both sides by 2

Divide both sides of the equation \(350 = 2(n + 80)\) by 2. We get \(\frac{350}{2}=n + 80\), which simplifies to \(175=n + 80\).

Step3: Solve for \(n\)

Subtract 80 from both sides of the equation \(175=n + 80\). So, \(n=175 - 80\).

Answer:

\(n = 95\) meters
