A sheet metal worker needs to cut a piece of metal in the shape shown below. What is the EXACT length of the longest side of this triangle?

Could you make it more clear?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
