Discussion :: Area

The area of a rectangle is equal to the area of rightangles 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.
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 
Answer : Option D
Explanation :
Given: Area of rectangle = Area of a rightangles triangle.
l x b =\(\frac { 1 } { 2 } \)xBxH
I gives, B = 40 cm.
II gives, H = 50 cm.
Thus, to find l, we need b also, which is not given.
Given data is not sufficient to give the answer.
Correct answer is (D).
