2. a square and a equilateral triangle have the same perimeter. what is the perimeter of each shape?

equilateral triangle P = x + 2

**drwls**, Wednesday, June 9, 2010 at 7:57pm1. (84 + 96 + 88 + x)/4 = 90

Solve for x.

2. Read the question again. They already told you the perimeters are the same.

You cannot say what the perimeter is with the information you have provided. All you know is that they are equal.

**drwls**, Wednesday, June 9, 2010 at 8:04pmSolve the equation I wrote for you.

The next step would be to rewrite it as

268 + x = 4*90 = 360

Then subtract 268 from sides.
