Answer:
The area of the triangle is (3x-6) in² .
Step-by-step explanation:
You have to apply area of triangle formula :
[tex]area = \frac{1}{2} \times base \times height[/tex]
Then, you have to substitute the following expressions into the formula :
[tex]let \: base = 2x - 4 \\ let \: height = 3[/tex]
[tex]area = \frac{1}{2} \times (2x - 4) \times 3[/tex]
[tex]area = \frac{3}{2} \times (2x - 4)[/tex]
[tex]area = \frac{6}{2} x - \frac{12}{2} [/tex]
[tex]area = (3x - 6) \: {in}^{2} [/tex]
