Answer:25 cm
Step-by-step explanation:
As, the diagonals of a rhombus cut each other in 2 equal parts and at a right angle .
Side²=(30/2)²+(40/2)²
Side²=15²+20²
Side²=225+400
Side²=625
Side=√625
Side=25 cm
Side of rhombus=25 cm

Answer:
25 cm
Step-by-step explanation:
The rhombus can be split into 4 right angled triangles.
two sides of each triangle would be 15 cm and 20 cm.
we have to find the side, i.e., the hypotenuse.
using pythagoras theorem:
a²+b²=c²
⇒15²+20²=c²
⇒225+400=625
c²=√625
=25
ans: 25 cm
