To answer this, you will represent the new side length of the square as x + 6.
To find the area you will multiply (x + 6) by (x + 6).
To do this, you will multiply x and x, x by 6 twice and 6 by 6.
See the attached picture for the expression representing the area of the new square.
All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary).
All sides are congruent by definition.
The diagonals bisect the angles.
