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
