The area Model that would be used to multiply is 3x^3 + 12x^2 + 15x
Area of a rectangle
The formula for calculating the area of a rectangle is expressed as:
A = length * width
Given that
Length = 3x
Width = x^2+4x+5
Taking the product
A = 3x(x^2+4x+5)
A = 3x^3 + 12x^2 + 15x
Hence the area Model that would be used to multiply is 3x^3 + 12x^2 + 15x
