Find the area of an equilateral triangle using apothem length 6. PLEASE put in simplified radical form

Pls , the question is in the picture!

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Someone me! if you’re smart you can solve this!
