The perimeter of a rectangle is (2 lengths) plus (2 widths).
If one side is missing, then it sounds like you still have enough information
to know what the length and the width are. Just take each number and use
the first line up there /\ to calculate the perimeter with them.
Steps for multiplying the given binomial and trinomial 
are:
Step 1: 
Step 2: 
Step 3: 
Surface Area of the Prism = (6x4) = 2(5x4) + 2(1/2x6x4)
Surface Area of the Prism = 24 + 40 + 24
Surface Area of the Prism =88 cm²
