Prepare for this short essay.

Find a tape that measures in cm. If yours only measures in inches, convert inches to cm's. Measure your height and type it below; now measure the length of your arms stretched out from fingertip to fingertip and type it below, now divide the two numbers and type the answer below. The closer the answer is to 1, the more "square" you are. If it is not 1, you are a rectangle. Professional basketball players are often rectangles because their arms are so long!
