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:
[tex]\begin{gathered} 9\text{ in=36 yards,} \\ 6\text{ in=24 yards.} \end{gathered}[/tex]
Substituting the above values in the formula for the area of a triangle, we get:
[tex]A=\frac{36\text{yards}\cdot24\text{yards}}{2}\text{.}[/tex]
Simplifying the above result, we get:
[tex]A=\frac{864}{2}squareyards=432\text{ square yards.}[/tex]
Answer:
[tex]A=432\text{ square yards.}[/tex]
