Question
If the diagonals of a rhombus are 24cm and 10cm the area and the perimeter of the rhombus are respectively.
Options
A. 10
B. 11
C. 12
D. 13

Correct Answer

13

Explanation

Area = $\frac{1}{2} * d i a g o n a l 1 * \frac{1}{2} d i a g o n a l 2$ = $\frac{1}{2} * 24 * 10$ sq.cm

$\frac{1}{2} * d a i g o n a l 1 = \frac{1}{2} * 24 = 12 c m$

$\frac{1}{2} * d i a g o n a l 2 = \frac{1}{2} * 10 = 5 c m$

side of a rhombus = (12)� + (5)� = 169 => AB = 13cm
