15. 


Your Answer: Option (Not Answered) Correct Answer: Option A Explanation: From II, base : height = 5 : 12. Let base = 5x and height = 12x. Then, hypotenuse = (5x)^{2} + (12x)^{2} = 13x. From I, perimeter of the triangle = 30 cm. 5x + 12x + 13x = 30 x = 1. So, base = 5x = 5 cm, height = 12x = 12 cm.
Thus, I and II together give the answer. Clearly III is redundant, since the breadth of the rectangle is not given. Correct answer is (A). Learn more problems on : Area Discuss about this problem : Discuss in Forum
