A parallelogram has a base of 5 centimeters (cm) and a height of 12 cm and is stacked on top of a square with a side length of 5 cm. Hannah calculates the area of the parallelogram by multiplying the base and height to get 60 cm2, then dividing by 2 to get 30 cm2. She then multiplies the side length of the square by itself to find the area of the square, 25 cm2. Finally, she adds the areas together to find the area of the figure.
Is Hannah’s answer correct? Why or why not?
Select the option that correctly answers both questions.
-No, she incorrectly calculated the area of the square.
-No, she incorrectly calculated the area of the parallelogram.
-Yes, she correctly added the areas of the two figures to find the area of the composite figure.
-No, she mistakenly added the area of the square and triangle when she should have multiplied them.
