Answer is E

1. 2(l*b)=300 ==> no info on length and breadth of larger rectangle.
2. L*B=60000 , L and B can be any value such as 200, 300 or 20, 3000.

Combined insuff ==> No info on the number of smaller rectangles and the length and breadth

I agree that the correct answer is E. However, the 1st statement mentioned the Perimeter of the small rectangular, not the area.
Therefore, it is not 2*(Length*breadth) but 2*(Length + breadth).
Because we know that the 2 small rectangles have the same size, it could also be written 2*(Length + (Breadth of larger triangle)/2) = 2*Length + Breadth.

Baps, you're right that the 1st statement mentions the perimeter and not the area but there is 1 error (see highlighted) in your answer. The question does not tell us the number of small rectangles. I agree that this does not have an impact on our answer but in another situation/question, it just might! :)

That's very true, I completely misread the question. Thanks for spotting this mistake !
