Find the area of the parallelogram by imagining that the blue triangle is moved onto the purple triangle.
A 9 units² 2
B 15 units2
C 16 units2
D 2 18 units
To find the area of the parallelogram, we need to determine the base and the height of the parallelogram.
The base of the parallelogram is the length of the top side, which is 9 units.
To determine the height, we can imagine that the blue triangle is moved onto the purple triangle. By doing so, the height of the parallelogram remains the same. The height of the blue triangle is 2 units, so the height of the parallelogram is also 2 units.
Now we can calculate the area of the parallelogram by multiplying the base (9 units) by the height (2 units):
Area = base × height
Area = 9 units × 2 units
Area = 18 units²
Therefore, the area of the parallelogram is 18 units².
The correct answer is D) 18 units².
