Solution
The correct option is Cside−26cm,diagonals−20cm,48cm Its perimeter is 104cm Perimeter =4xside=104 => side =26cm The diagonals of a rhombus are in the ratio 5:12. Let diagonals are 5x and 12x Diagonals of rhombus are perpendicular to each other, so by applying Pythagoras theorem => a2=(5x2)2+(12x2)2 => 262=169x24 => x=4 Diagonals are 5x=20cm and 12x=48cm
