    Answer : Option D

    Explanation :

    Given: Area of rectangle = Area of a right-angles 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).
