Find the area of the shaded polygon

Area_poly = 570 mm^2 - 133 mm^2 = 437 mm^2

Step-by-step explanation:

The area of the shaded polygon is equal to the are of the whle rectangle minus thea area of the white triangle.

Rectangle area = l*h = 15mm*38 mm =  570 mm^2

Triangle area = base*height/2

Triangle area = (38mm)*(15mm-8mm)/2

Triangle area = (38mm)*(15mm-8mm)/2 = 133 mm^2

Area of the shaded polygon

Area_poly = 570 mm^2 - 133 mm^2 = 437 mm^2

idk lol
