Is it possible to draw a triangle whose sides have lengths 10.3cm, 5.8cm, 4.6cm

Yes it can be drawn

Here's your answer!!
We know that
Sum of the length of 2 sides of a triangle is equal to longest sides' length
Thus
4.6 cm
+5.8 cm
--------------------
10.4 cm
---------------------
Since 10.4cm > 10.3cm
Yes the triangle can be drawn

No. The other two length cannot exceed the base length.
