How to do this question plz

Step-by-Step Explanation:

Please refer to the attachment below.

So, notice that to find y, we simply need to determine x.

Remember that the area of a parallelogram is given by bh.

We can see that our base is x.

And our height h is half of 14. Therefore, h=7.

So, the area of one parallelogram is:

Then the area of four parallelograms is:

Since the total area of the shape is 308 squared centimeters. This means that:

Therefore:

Then it follows that:

this is answer of 144 cubic meters
