Final answer:
The total area of the shape can be found by multiplying the length of the base by the height of one of the congruent parallelograms. In this case, the total area is 198 square centimeters.
Step-by-step explanation:
The total area of the shape can be found by multiplying the length of the base by the height of one of the congruent parallelograms. Since the parallelograms are congruent, their base lengths and heights are the same. In this case, the base length is 18 cm and the height is 11 cm. Multiplying these values together, we get:
Total area = Base length x Height = 18 cm x 11 cm = 198 cm^2
Therefore, the total area of the shape is 198 square centimeters.
