and II” given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. What is the area of rectangle ABCD? Statement I : Perimeter of rectangle ABCD is 4.5 times of its breadth. Statement II : Difference between squares of adjacent pair of sides of rectangle ABCD is 5.4 times its breadth.Solution
From Statement I: 2 (l + b) = 9/2 b => l + b = 9/4 b => l = 5b/4 From Statement II: l2 – b2 = 27/5 b Combining statements I and II we will get the area of rectangle ABCD. Therefore, both the statements are required to answer the question.
