The diagonal of a rhombus are 12cm and 5cm. calculate its perimeter
A
26cm
B
24cm
C
17cm
D
34cm
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Perimeter of a Rhombus = 4L or 2\sqrt( d1\(^2\) + d2\(^2\))
P = 2\sqrt(12\(^2\) + 5\(^2\))
P = 2\sqrt(144 + 25)
P = 2\sqrt169 = 2 * 13
P = 26cm
