Answer:

  13x² -3x

Step-by-step explanation:

A horizontal line from the corner of the "notch" will divide the figure into two rectangles whose dimensions are given. The total area is the sum of the areas of those rectangles. Each area is the product of length and width.

  A = A1 + A2

  = x(3x-7) + 2x(5x+2)

  = 3x² -7x +10x² +4x

  = (3+10)x² +(-7+4)x

  = 13x² -3x

The area is 13x² -3x.
