Question 1105663
<br>
For a parallelogram, the area is base times height, just like a rectangle.  So if h is the height,
{{{4b^2 = b*h}}}
{{{4b = h}}}<br>
The height is 4b; you can find the answer to the question that is asked.<br>
-------------------------------------------------------<br>
The height is 4b; height minus base is 4b-b = 3b  --  answer C
