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
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
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
