    Question

    Area of a rhombus whose one of the diagonals (d1) is 28

    cm, is 560 cm2. Each side of a square paper is 20 cm more than other diagonal (d2) of the rhombus. Find the cost (in Rs.) of painting the square paper from both the surfaces at the rate of Rs. 0.25/cm2.
    A Rs. 1200 Correct Answer Incorrect Answer
    B Rs. 1600 Correct Answer Incorrect Answer
    C Rs. 1800 Correct Answer Incorrect Answer
    D Rs. 1700 Correct Answer Incorrect Answer

    Solution

    According to the question, {(d1 × d2)/2} = 560 Or, 28 × d2 = 1120 Or, d2 = 1120/28 = 40 Therefore, each side of the squared paper = 20 + 40 = 60 cm Required cost of painting = 2 × 60 × 60 × 0.20 = Rs. 1800
