Factoring by grouping usually pairs up the first 2 sets of expressions with the second 2 sets. Ours looks like this, then: 
. If we factor out the common x-squared in the first set of parenthesis, along with factoring out the common 5 in the second set, we get this: 
. Now the common expression that can be factored out is the (x-9). When we do that, here's what it looks like: 
. I'm not sure how far you are going with this. You could set each of those equal to 0 and solve for x in each case. The first one is easy. If x - 9 = 0, then x = 9. The second one involves the imaginary i since x^2 = -5. In that case, 
. Hopefully, in what I have given you, you can find what you're looking for.
The perimeter is the sides of the hexagon. One of the hexagon edges is shared with a rectangular face. Solve for that edge. 78/6=13. The height is the length and edge is the width. Area is length(16) times width(13). 16•13=208. The answer is 208mm^2
