Solution

The correct option is A 24 cm2
The three sides are 10 cm, 6 cm and 8 cm.

62+82=36+64=100=102

By converse of Pythagoras theorem, the triangle is a right-angled triangle. Let's take the sides 6 cm and 8 cm as the base and the height respectively.
Area of a triangle =12×base×height
Area=12×6×8 cm2
=24 cm2
