I dont know what math this is and I dont know how to calculate it. But I'm modeling an insert for a robot, this smaller rectangle is to hold the battery. I want it to all be uniform but as you can see the rectangle is touching the edges as I intended but the the top distance from the top right corner of the small box is bigger than the distance between the left edge of the box to the top left corner of the smaller box. Sorry it's a bit confusing how to word it but hopefully you can help me and understand my problem.
