Question
The question consists of two statements numbered “I
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.
