For this case we must find the area of the triangle shown in the figure.
The area of a triangle is given by:
[tex]A = \frac {b * h} {2}[/tex]
Where:
From the figure we know that:
[tex]b = 15\ in\\h = 18\ in[/tex]
Substituting we have:
[tex]A = \frac {15 * 18} {2}\\A = 135[/tex]
Thus, the area of the triangle is [tex]135\ in ^ 2[/tex]
Answer:
[tex]135\ in ^ 2[/tex]
