Find the missing side of the placemat shown if the perimiter is 28x + 11 inches

Step-by-step explanation:

I can find the side using perimeter only if all sides are equal. I'm assuming the placemat is a square. Then 4x=28x+11. Solve for x:

Step 1: subtract 28x from both sides.

4x-28x=28x+11-28x; -24x=11

Step 2: divide both sides by -24.

.

That should be the x=-11/24
