Explain how to find the area of the figure. show step and write your answer in factored form

5x(x+4)

Step-by-step explanation:

break the figure into 2 parts  the rectangle and the triangle

rectangle:  2x* (2x+6)

                 4x^2 + 12x

triangle = 1/2 b*h

              = 1/2(2x) * (x+8)

             = x* (x+8)

            x^2 + 8x

add the two parts together

   4x^2 + 12x+  x^2 + 8x

4x^2 + x^2 + 12x+8x

5x^2 + 20x

factor out a 5x

5x(x+4)

{3 + i, 3 - i, 3, -1}
