Answer:
Perimeter of rectangle before folded = 56 in
Total area after folding = 156 sq in
Step-by-step explanation:
Rectangle before folded:  l = 16 and w = 12
                                            P = 2(16) + 2(12) = 32 + 24 = 56 in.
Figure after folding:   Area of trapezoid + area of rectangle
Area of trapezoid = h( )/2 = 6(4 + 16)/2 = 60
)/2 = 6(4 + 16)/2 = 60
Area of rectangle = lw = 16(6) = 96
Total area after folding = 60 + 96 = 156 sq in.
Note:  You could also find the area after folding by substracting the areas of the two triangles in the corners from the area of the original rectangle.  Your choice.  OK?
