Answer:
Part 1) The lateral area is 
Part 2) The area of the two bases together is 
Part 3) The surface area is 
Step-by-step explanation:
Part 1) Find the lateral area
we know that
The lateral area of a prism is given by

where
P is the perimeter of the base
h is the height of the prism
so
----> perimeter of rectangle
---> given
substitute

Part 2) The area of the two bases together is?
The area of the rectangular base B is equal to

therefore
The area of the two bases together is

Part 3) The total surface area is
we know that
The surface area is equal to

substitute
