\frac{1}{2}×base×hight
\frac{1}{2}×15\frac{1}{4}×18
\frac{1}{2}×\frac{61}{4}×18
137.25 in²

To find the area of a triangle, we can use the formula \frac{1}{2} bh, 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\frac{1}{2} * 15 \frac{1}{4} * 18. Well, we can multiply one half with 18 to get 9, and all we need to do is multiply 15 \frac{1}{4} with 9.

We get the grand total of 137.25 inches.
