To determine the area of the polygon, we need to break it down into smaller shapes to calculate the total area.
The polygon can be divided into a rectangle and two triangles.
Rectangle:
Length = 20 cm
Width = 7 cm
Area of rectangle = Length x Width
Area of rectangle = 20 cm x 7 cm
Area of rectangle = 140 square cm
Triangle 1:
Base = 10 cm
Height = 7 cm
Area of triangle 1 = 1/2 x Base x Height
Area of triangle 1 = 1/2 x 10 cm x 7 cm
Area of triangle 1 = 35 square cm
Triangle 2:
Base = 10 cm
Height = 6 cm
Area of triangle 2 = 1/2 x Base x Height
Area of triangle 2 = 1/2 x 10 cm x 6 cm
Area of triangle 2 = 30 square cm
Total area of the polygon = Area of rectangle + Area of triangle 1 + Area of triangle 2
Total area of the polygon = 140 square cm + 35 square cm + 30 square cm
Total area of the polygon = 205 square cm
Therefore, the area of the polygon is 205 square centimeters.

I apologize for the mistake in my calculation. Let's reevaluate the area of the polygon.
The polygon can be divided into a rectangle and two triangles.
Rectangle:
Length = 20 cm
Width = 7 cm
Area of rectangle = Length x Width
Area of rectangle = 20 cm x 7 cm
Area of rectangle = 140 square cm
Triangle 1:
Base = 10 cm
Height = 7 cm
Area of triangle 1 = 1/2 x Base x Height
Area of triangle 1 = 1/2 x 10 cm x 7 cm
Area of triangle 1 = 35 square cm
Triangle 2:
Base = 10 cm
Height = 6 cm
Area of triangle 2 = 1/2 x Base x Height
Area of triangle 2 = 1/2 x 10 cm x 6 cm
Area of triangle 2 = 30 square cm
Total area of the polygon = Area of rectangle + Area of triangle 1 + Area of triangle 2
Total area of the polygon = 140 square cm + 35 square cm + 30 square cm
Total area of the polygon = 205 square cm
Therefore, the area of the polygon is 205 square centimeters.
The closest provided response is 268 square centimeters.
Let's reevaluate the area of the polygon.
Rectangle:
Length = 20 cm
Width = 7 cm
Area of rectangle = Length x Width
Area of rectangle = 20 cm x 7 cm
Area of rectangle = 140 square cm
Triangle 1:
Base = 10 cm
Height = 7 cm
Area of triangle 1 = 1/2 x Base x Height
Area of triangle 1 = 1/2 x 10 cm x 7 cm
Area of triangle 1 = 35 square cm
Triangle 2:
Base = 10 cm
Height = 6 cm
Area of triangle 2 = 1/2 x Base x Height
Area of triangle 2 = 1/2 x 10 cm x 6 cm
Area of triangle 2 = 30 square cm
Total area of the polygon = Area of rectangle + Area of triangle 1 + Area of triangle 2
Total area of the polygon = 140 square cm + 35 square cm + 30 square cm
Total area of the polygon = 205 square cm
After recalculating, the area of the polygon is confirmed to be 205 square centimeters. Thank you for your patience.
