To find the area of a rectangle we multiply two edges together.
since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)
ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal
2(1x2) + 4(3x2) = 4 + 24 = 28

Step-by-step explanation:
3x + (2x + 4) is equivalent to (3x + 2x) + 4
because there is no change of signs taking place as there is no (-) sign in front of the brackets
3x + (2x + 4) | (3x + 2x) + 4
3x + 2x + 4 | 3x + 2x +4
5x + 4 | 5x + 4
