The diagonals of a rhombus are 16 cm and 12 cm, in length. The side of the rhombus in length is:
Here, half of the diagonals of a rhombus are the sides of the triangle and side of the rhombus is the hypotenuse.
By Pythagoras theorem,
$(\dfrac{16}{2})^2+(\dfrac{12}{2})^2=side^2$
$8^2+6^2=side^2$
64+36=$side^2$
$side^2$ = 100
side=10 cm
