Solution:
We know that:
[tex]Area \ of \ triangle = \dfrac{1}{2} \times Base \times Height[/tex]
Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.
[tex]Area \ of \ triangle = \dfrac{1}{2} \times 18 \times24[/tex]
Cancel out the "2" by dividing it by 18.
[tex]Area \ of \ triangle = 9 \times24[/tex]
Simplify the multiplication.
[tex]\bold{Area \ of \ triangle = 216 \ ft^{2}}[/tex]
