The formula for finding the perimeter of an equilateral triangle is P = 3s. How can you transform the
formula so that it can be used to determine the length of one side of the triangle when given the
perimeter?

3. Liv, you are just shuffling the letters around.
Surely you can't think that
3P=s, Ps=3 and P=3s are all the same.

P = a + b + c
P = 3s (equilateral)
2. Square
P= 4s
3. Rectangle
P = 2l + 2w or P = 2(l + w)
