Question
Find the area of a rhombus. A.
Sum of the squares of the diagonals is 256 m². B. Perimeter of the rhombus is 32 m. C. Ratio of one diagonal and the side is 3:8 The following questions are accompanied by three statement A, B and C. you have to determine which statement (s) is /are necessary/ sufficient to answer the question.Solution
If d₁ and d₂ be the diagonals and a the length of the side of the rhombus then A. d₁²and d₂² = 4a² = 256 a² = 64 a = 8 P = 4a 32 = 4a 4 = a C. d₁ : a = 3 : 8 Therefore, by combining C and either A or B, the answer can be found.
