How do I find the perimeter of of a square ? I have equations on the sides too like 4x-7, but I dont know the exact numbers. I have 3/4 sides too. Can someone explain how to find the solution? Thank you (:

All sides of a square are equal. Set up all the relationships you can find.

You should have basic equation solving well in hand by the time you get such a question. y + 3 = 0 ==> y = -3 2y = 4 ==> y = 2 2y - 4 = 6 ==> 2y = 10 ==> y = 5

Do that thing in my first drawing. Set up equations. There are three possible.

They are all equal. Just pick two.

Of course, it will also help to write them correctly. 3x + 9 = 9 - 2x Subtract 9 3x = -2x x = 0 <== That's a pretty small square.
