Determine the formula of one of the triangular sections
From the attachment, we have that:
The area of the triangle is:
<u>How to know the formula works?</u>
From the attachment, we can see that the rectangle is divided into two equal triangular sections.
The area of the rectangle is:
Because the rectangle is divided into two equal triangular sections.
This implies that, the area of one of the triangular sections is half the area of the rectangle.
So:
Substitute LB for the area of the rectangle
By comparison:
and are the same
