Rectangle ABCD is divided into five identical rectangles. If the perimeter of ABCD is 132, what is the length of side BC?

A. 24
B. 27.5
C. 30
D. 33
E. 36


P.S: Bunuel- how to approach this type of questions?
I believe must be the answer as when divided by 5 it gives a whole number. And my answer would be correct with an alteration to the question stating that the sides of the identical triangles are integers & BC being the shorter side of the rectangle.

Only two answers give you sides that are evenly divisible by 5. "C" makes BC one of the two sides that's divided into five even parts. Answer "E" is just the opposite-Side AB would be one of the two evenly divided by five sides. I went with C as it was obvious without calculating.

I agree with above comments that it's a poor quality question, so I wouldn't worry about it at all.
