What is the height of the triangle?
I.	The area of the triangle is 20 times its base.
II.	The perimeter of the triangle is equal to the perimeter of a square of side 10 cm.
Select the correct option:
A) I alone sufficient while II alone not sufficient to answer  B) II alone sufficient while I alone not sufficient to answer  C) Either I or II alone sufficient to answer  D) Both I and II are not sufficient to answer  E) Both I and II are necessary to answer
EXPLANATION   I. A = 20 x B ⇒1-div-1by2 x B x H = 20 x B⇒H = 40.   I alone gives the answer.   II gives, perimeter of the triangle = 40 cm.   This does not give the height of the triangle.   answer is (I alone sufficient while II alone not sufficient to answer).
