L and J are standing in a ground.?
We have a description of a four-sided polygon (let's call the vertices LH, LT, JH, and JT) with three sides lengths given. This can be divided into a lower rectangle and upper right-triangle; with the lengths of the sides of the triangle being of length LTJT (110) and (JH-LH) (96). The length of the hypotenuse is then simply the square root of the sum of the squares of the sides: (110^2 + 96^2) ^1/2= (12,100 + 9,216)^1/2= (21,316)^1/2 = 146 cm
