Abase ball diamond has four right angles and four equal sides each side is 90 feet what is the shortest distance between home plate and second base round your answer to the nearest tenth

This question can be answered with the pythagorean theorem, or a^2 + b^2 = c^2.  We can make a triangle out of the square by drawing a line from home plate to second base.  This straight line will be the shortest way to the second base.  The home plate to first base line and first base to second base lines are both 90 feet.

90^2 + 90^2 = c^2.  c is the distance from home plate to second base.  We now solve for c.  We do this by adding 90^2 + 90^2 and taking the square root of the number we get.  This equals 127.3 feet.
