Answer:
5 cm

Step-by-step explanation:
In a rhombus,
1 diagonal = 8 cm (left - right)
2 diagonal = 6 cm (top - bottom)

There will be 4 triangles in a rhombus when bisected with 2 intersecting diagonals (all 4 will have equal measures).

Then,
Base of 1 triangle = 8/2 = 4 cm
Altitude of 2 triangle = 6/2 = 3 cm

Hypotenuse of 1 triangle = Longest side of triangle = Side of rhombus = ?

Using pythagorean property,
√((4)² + (3)²) = Hypotenuse
√(16 + 9) = Hypotenuse
√25 = Hypotenuse
5 cm = Hypotenuse = 1 side of rhombus

Answer:

[tex]\huge\boxed{\bf\:5\: cm}[/tex]

Step-by-step explanation:

Let's take a rhombus with diagonals AC & BD which intersects at point E.

Take,

  • AC = 8 cm
  • BD = 6 cm

Now, we need to find the length of a side of a rhombus.

For this, let's take one part of the rhombus, say, △AED.

Now, since E is the midpoint of diagonals AC & BD,

  • AE = AC/2 = 8/2  = 4 cm
  • ED = BD/2 = 6/2  = 3 cm

AE will form the altitude & ED the base of  △AED.

Then, in  △AED, by following the pythagorean theorem,

Hypotenuse² = Base² + Altitude²

Hypotenuse² = 3² + 4²

Hypotenuse² = 9 + 16

Hyptenuse² = 25

Hypotenuse = √25

Hypotenuse = 5 cm

From the figure we can see that the hypotenuse of  △AED forms one side of the rhombus. Since all the sides of a rhombus are equal, 5 cm is the measurement of the length of a side of the rhombus.
