can someone please help me with this question?

Answer: x = 8
Step-by-step explanation:
The area of a triangle can be found using the formula [tex]\frac{h*b}{2} = Area[/tex], where
h = the height of the triangle
b = base of the triangle
In this case, the height of the triangle is x, and the base is 4, while the total area is 16 [tex]units^{2}[/tex].
We can substitute that into the area equation, and we will get [tex]\frac{x*4}{2} =16[/tex]
1) Multiply both sides by 2
You will get x * 4 = 32
2) Divide both sides by 4
You will get x = 8
So, x will have a length of 8 units.
