To answer this question, first, we transform the base and the height from inches to yards.
Since the scale is 1 in : 4 yards, then:
![\begin{gathered} 9\text{ in=36 yards,} \\ 6\text{ in=24 yards.} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8f4666lntg88izfjpdw5b3oamu01k4zlmr.png)
Substituting the above values in the formula for the area of a triangle, we get:
![A=\frac{36\text{yards}\cdot24\text{yards}}{2}\text{.}](https://img.qammunity.org/2023/formulas/mathematics/college/q074m4t71snmfo3m7l0o6bhlvevgeugkl9.png)
Simplifying the above result, we get:
![A=(864)/(2)squareyards=432\text{ square yards.}](https://img.qammunity.org/2023/formulas/mathematics/college/3u5kd4vfaxtkhfqtxyxz1azfpjby12xdwa.png)
Answer:
![A=432\text{ square yards.}](https://img.qammunity.org/2023/formulas/mathematics/college/tgm4m5rmqx2ssuwwiqxd5ks2gglfeze6is.png)
