can the answer not be C?
with st1 we can get AD=BC=4 (since abcd is a rectangle) which are heights of the 2 right-angled triangles resp and from st2 we have AE & BE which are bases of 2 right-angled triangles resp.
then we can find the 2 areas using formula (base*ht)/2
As explained above, to answer the question, you don't need the first statement at all; the second statement alone is enough. This means that the answer is B: Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
Below are the options for DS questions, and what they mean:
The data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether—
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
C. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
D. EACH statement ALONE is sufficient to answer the question asked.
E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
