Write an equation to represent this situation and answer the question. You may choose to use the 5-D Process to help you organize your thinking.
Ella is trying to determine the side lengths of a triangle. She knows that the longest side is three times longer than the shortest side. The medium side is ten more than twice the shortest side. If the perimeter is
Create a variable expression for perimeter to represent this problem with the shortest side defined by
How do the other sides relate to the shortest side, or
Shortest Side:
Medium side:
Longest Side:
Add the lengths of the sides and set equal to the perimeter in order to solve for
Shortest Side:
What are the lengths of the other sides?
