The area formula of a triangle is $$b \times \frac{ h }{ 2 }$$ The height of the triangle is 0.8cm.  So 0.8cm divided by 2 equals 0.4.  Now that you know what the height divided by 2 is, you can substitute numbers for variables.

The next thing you need to do is this. $$2.4\times0.4=?$$ The answer you should get is 0.96...therefore$$2.4\times0.4=0.96$$ Does that help?
