You are also told that the length is twice the width so \[p = 2 q.\] You are also told that the perimeter is 150 meters. What is the perimeter in terms of $p$ and $q?$ This expression is equal to 150 meters so now you have two linear equations in $p$ and $q.$ Solve this pair of equations for $p$ and $q.$ Make sure you verify your answer. Write back if you need more assistance.
