Area of each smaller rectangle= 75*100/20=375. If we know the dimension of any side, we can calculate the dimension of the adjacent side. Once we know the exact dimension of the smaller rectangles, we will know how many inches of lines will be needed to divide the original rectangle-- the lines will be cut along the perimeter of the rectangles, each of the lines will be shared by two rectangles, and the perimeter of the original rectangle need not be cut.
1) One of the dimension of each of the rectangles is 15 inches, the other is therefore= 375/15=25. Sufficient
2) One of the dimension of each of the rectangles is 25 inches, the other is therefore= 375/25=15. Sufficient
Answer is D.

Bunuel,
Is the answer D?
(1) Division has to be along the 75 inches side for equal rectangles
(2) Division has to be along the 25 inches side for equal rectangles
