The area and a diagonal of a rhombus are 60 cm(^2) and 12 cm respectively. Calculate the length of the other diagonal.

  • A.
    5cm
  • B.
    6cm
  • C.
    10cm
  • D.
    12cm
  • E.
    15cm
Correct Answer: Option C
Explanation

Area of rhombus = (frac{pq}{2})

where p and q are the two diagonals of the rhombus.

(therefore 60 = frac{12 times q}{2})

6q = 60 (implies) q = 10 cm
