I don’t really know what your asking but anything multiplied by 0.5 or .5 is going to be half of that number
Example 2•.5=1
I don’t know if this is what you were asking, but I hope this helps
Here is the answer that Siri gave me
Measure the sides. And when you get all of the sides add them I'll and get the perimeter I think.
It would be 14y.... if you combine like terms you would get the following:
7(2y)
7•2
14y
