Answer:
D) 16 square units
Step-by-step explanation:
The base can be considered to be the line x=-3. The extent of the triangle along that line is from y=-4 to y=4, so is 8 units.
The "height" of the triangle can be considered to be the distance from the vertex at x=-7 to the line at x=-3, so is 4 units.
The area of the triangle is half the product of these measures:
A = (1/2)bh = (1/2)(8 units)(4 units) = 16 square units
