Step-by-step explanation:

Given,

• length of diagonal of rhombus=30 cm and 40 cm
• let's take ABCD as rhombus with diagonals AD=40cm and BC=30cm with the intersecting point O of diagonals.
• AD/2=40cm/2= 20 cm
• BC/2=30cm/2= 15 cm
• As the AOB is right angled at Owe can use phythagoras theorem to find side of rhombus.
• (adjacent side)^2+(opposite side)^2=(hypotenuse)^2
• (20 cm)^2+(15cm)^2= x^2
• 400+225=x^2
• 625=x^2
• x=25

Hence,the side of rhombus is 25 cm
