  1. Question 1

    Q1. The area of a rhombus in 2016 Sq.cm and its side is 65cm. The length of its diagonals are________?

    • A) 125cm, 35cm
    • B) 126cm,32cm
    • C) 132cm,26cm
    • D) 135cm,25cm

    Answer: 126cm,32cm

    Explanation: Half-diagonals a and b satisfy a²+b²=65²=4225 and (1/2)×2a×2b=2016, so ab=2016. Solving: diagonals are 126 cm and 32 cm (63²+16²=3969+256=4225 ✓).
