The area of the entire rectangle is 4x² + 12x + 8
How to determine the area of the entire rectangle?
The given parameters are:
height = 4
Width = x² + 3x + 2
The area of the rectangle is:
Area = Width * Height
So, we have:
Area = (x² + 3x + 2) * 4
Expand
Area = 4x² + 12x + 8
Hence, the area of the entire rectangle is 4x² + 12x + 8
