Answer:
141.12 cm^2
Step-by-step explanation:
Since the area of a trapezoid is the average of the bases multiplied by the height, we can just plug these numbers into the equation! Since the average of 10.2 and 12.2 is 11.2, and the height is 12.6, we multiply them to get the area to be 141.12 cm^2.
Let's solve for x.

Answer: 17/3
Step-by-step explanation:
Because this is a parallelogram, we know that the diagonals bisect. This means that AO = DO, and CO = BO
It doesn't matter which two segments we use, but I'm going to use CO = BO for this one.
3x - 7 = x - 1
2x = 6
x = 3
