Answer: 28
Step-by-step explanation:
The shape is grouped into 4 identical parallelograms.
Thus, as the combined area of the figure is 308, you can divide 308/4 to get 77. Thus, each parallelogram has an area of 77.
Then, divide 14/2 to get that the height of each parallelogram is 7.
The area of a parallelogram is l*w. Thus, because l = 7, each parallelogram has a width of 11 because 77/7 = 11.
Then, simply add 11+11+6 to get y.
