A rectangle's area is equal to a right-angles triangle's area. What is the rectangle's length? I. The triangle's base measures 40 cm. II. The triangle's height is 50 cm.
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

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
Explanation: Assume that the area of a rectangle equals the area of a right-angles triangle.1/2 x B x H = l x b.B = 40 cm, according to I.H = 50 cm, according to II. To find l, we also require b, which isn't supplied.Data alone isn't enough to make a decision.
