Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the lengt

h of the shortest side, and the third side will be twelve feet long. What expression could she write to determine the perimeter of the triangle if s represents the length of the shortest side? (Recall that perimeter is the distance around a shape.) What is the expression in simplified form? What is the coefficient of the variable in the simplified expression?

The simplified expression would be 3s + 15.

In order to find this we need to write an equation for the longest side. Since it's 3 more than twice as much as the smallest side (s), we can express it as 2s + 3. Now we simply add all 3 together and simplify.

2s + 3 + 12 + s -----> simplify

3s + 15
