Now by seeing this attached picture we can say that 8 cm +8 cm = 16 cm and 15 cm + 15 cm = 30 cm...
since diagonal of a rhombus bisects each other
now by applying Pythagoras theorem we get,
h² = p² + b²
h² = 8² + 15²
h² = 64 + 225
h² = 289
h = √289
h = 17
therefore perimeter of the rhombus ,
= 4 * side
= 4 * 17
= 68 cm
therefore perimeter of the rhombus = 68 cm
