Answer:
Third option: [tex]8\ ft^2[/tex]
Step-by-step explanation:
The area of a triangle can be calculated with the following formula:
[tex]A=\frac{bh}{2}[/tex]
Where "b" is the base and "h" is the height of the triangle.
In this case you know that this triangle has a base of 4 feet and a height of 4 feet, then:
[tex]b=4\ ft\\h=4\ ft[/tex]
Therefore, you can substitute these values into the formula, getting that the area of this triangle is:
[tex]A=\frac{(4\ ft)(4\ ft)}{2}\\\\A=8\ ft^2[/tex]
