Question
Area of a rhombus whose one of the diagonals (d1) is 50
cm, is 450 cm2. Each side of a square paper is 26 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.Solution
According to the question, {(d1 × d2)/2} = 450 Or, 50 × d2 = 900 Or, d2 = 900/50 = 18 Therefore, each side of the squared paper = 26 + 18 = 44 cm Required cost of painting = 2 × 44 × 44 × 0.2 = Rs. 968
