Area Of A Triangle

To find the value of , we use the formula for the area of a triangle with vertices , , and : Substitute the given vertices into the formula. The vertices are , , and . So, , , , , , and . Now, substitute these into the area formula: Simplifying the expression: Given that the area is 35 square units, set the equation equal to 35: Now, solve for : 1. 2. Since the value of must be a reasonable integer and corresponds to the first equation, we conclude that: Thus, the correct answer is (A) 4.
