Chapter 16.2, Problem 4PS

To determine

To find: Thearea of $\Delta TRY$ .

Answer to Problem 4PS

The area of $\Delta TRY$ is $292\frac{1}{2}{\text{unit}}^2$ .

Explanation of Solution

Given information:

The given figure is,

  

The area of $\Delta TRY$ is calculated as,

  $\begin{array}{c}A=\frac{1}{2}\left|\left(-8\right)\left(-2\right)+12\left(25\right)+3\left(-7\right)-\left(-8\right)\left(25\right)-12\left(-7\right)-3\left(-2\right)\right|\\ =292\frac{1}{2}{\text{unit}}^2\end{array}$

Thus, the area of $\Delta TRY$ is $292\frac{1}{2}{\text{unit}}^2$ .
