To calculate the area of the triangle you have to multiply its base by its height and divide the result by 2, following the formula
![A=(bh)/(2)](https://img.qammunity.org/2023/formulas/mathematics/high-school/xo42jv4osrwdvc7knat7xohbopzvkw08x9.png)
Considering the given right triangle, the base and the height of the triangle are its legs:
The area can be calculated as:
![\begin{gathered} A=(bh)/(2) \\ A=(7\cdot24)/(2) \\ A=(168)/(2) \\ A=84ft^2 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ufl7sg5dv1xzfirb2tka7iyk7nxhamftlf.png)
The area of the triangle is 84ft²
