Step-by-step explanation:
The diagonal of a rhombus are 24cm and 10 cm. Find the length of a side of the Rhombus.
___________________________________
☆Let ABCD be the rhombus where, AC= 10cm and BD= 24cm
☆Let AC and BD intersect each other at O.
☆Now, diagonals of rhombus bisect each other at right angles.
☆Thus, we have
➛AO= ½ ×AC= ½ ×10=5cm
➛BO= ½×BD= ½×24= 12cm
☆In right angled △AOB,
⇒ (AB)² =(AO)² +(BO)²
⇒ (AB)² =(5)² +(12)²
⇒ (AB)² =25+144
⇒ (AB) ² = 169
∴ AB= 13cm
∴ The length of each side of rhombus is 13cm.
