The length if the upper portion of the stand is 33. 56 inches
<h3>How to determine the length</h3>
The formula for the finding the length is given thus;
Total height = length of upper portion + length of base
Where
Length of base = 257/16
Total height = 591/2
Length of upper portion = total height - length of base
= 118/2 - 407/16
= 59 - 25. 44
= 33. 56 inches
Thus, the length if the upper portion of the stand is 33. 56 inches
