Answer 1

well it's made up of 3 rectangles, 2 big and 1 small

SA of 1 rectangle = 48 - 2 (subtract area where small rectangle intersects)
Therefore 2 rectangles = 92

Area of small rectangle = 12

Total area = 92 + 12, or 104

pretty sure this is right, just added it up rather quickly tho

Answer 2

Thank you.
