surface area of a prism, length of bases

[heavens_daughter]

here is what I came up with for the answers to the following questions- my answers in blue. can someone please check and see if i got these right?

If the answer to an exercise cannot be determined, choose “cannot be determined” and explain your reasoning.

1. The base of a square prism has sides of 14 in.What is the surface area of the prism?
A. 56 in.2 B. 196 in.2 C. 784 in.2 D. cannot be determined

d. the problem doesnt give a height

2. A trapezoid has height 8 and area 28.What are the lengths of its bases?
F. 6 and 1 G. 5 and 2 H. 4 and 3 I. cannot be determined

I. none of the answers give the correct area when they are computed.

You had better look up the formula for the area of a trapezoid and do #2 over. I agree with your answer selection but not your reasoning.
