The diagonals of a rhombus WXYZ intersect at M. If |MW| = 5cm and |MX| = 12cm, calculate its perimeter
-
A.
42cm -
B.
48cm -
C.
52cm -
D.
60cm
Correct Answer: Option C
Explanation
Let the length of a side of the rhombus be n
Then, n(^2) = 5(^2) + 12(^2)
= 25 + 144 = 169
n = (sqrt{169})
= 13cm
Hence, perimeter of rhombus = 4n = 4 x 13
= 52cm
