Answer:
54, 60
Step-by-step explanation:
The equation for a triangle is 1/2LW= A. So multiply the length (12ft) and the height (9ft), then divide it by half: 12x9=108, 108/2=54. For the parallelogram, you solve it the same way you solve a rectangle, LW=A. The height is the along dotted line with the right angle, going up the side of the parallelogram with give you the wrong answer. 6x10=60 (posting as an answer, originally in the comments)
