Answer:
width (w) = 3
Step-by-step explanation:
The Area of a Rectangle = l * w
Where
l = length
w = width
From the question,
Area (A) = 3x²+6x-12
Length (l) = x² + 2x -4
To solve for width, let's rearrange the area.
A = 3x²+6x-12
A = 3 ( x²+ 2x -4)
From (A = lw)
Let's substitute the values:
3 ( x²+ 2x -4) = w * x² + 2x -4
Divide both sides by (x² + 2x -4)
3 = w.
Therefore, width (w) = 3
