In rectangle ADEH above, BG and CF are parallel to AH. Given lengths AB = 2, BC = 1, CD = 3, and the length of DH, not shown, is equal to 10, what is the area of the small rectangle BCFG?
(A) 8
(B) 10
(C) 16
(D) 24
(E) 48

The area of small rectangle BCFG is L*W. Its width, BC = 1
Find its length from the given length of the diagonal of the larger rectangle. DH = 10
∆ ADH
