To find the area of a triangle, we can use the formula [tex] \frac{1}{2} bh[/tex], where b is base and h is height.
We can then substitute the variables with our measurements. We then end up with an equation of[tex] \frac{1}{2} * 15 \frac{1}{4} * 18[/tex]. Well, we can multiply one half with 18 to get 9, and all we need to do is multiply [tex]15 \frac{1}{4} [/tex] with 9.
We get the grand total of 137.25 inches.
