The area formula of a triangle is
<span>b×h2</span> 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.
<span>2.4×0.4=?</span> The answer you should get is 0.96...therefore
<span>2.4×0.4=0.96</span>
<span /><span>
</span> Does that help?
