The area of a rectangle is equal to the area of right-angles triangle. What is the length of the rectangle?
I.	The base of the triangle is 40 cm.
II.	The height of the triangle is 50 cm. Select.
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   Given: Area of rectangle = Area of a right-angles triangle.   ⇒l x b =1-div-1/2x B x H   II gives, H = 50 cm.I gives, B = 40 cm.   Thus, to find l, we need b also, which is not given.   Given data is not sufficient to give the answer.   answer is (Both I and II are not sufficient to answer).
