Question 81678
If the sides are 3/4x,5/x^2,1/x^2, then you must ADD these sides together to get the perimeter.  This means you need to find a common denominator, which is 4x^2.  It looks like this:

{{{ (3/(4x)) +(5/(x^2)) + 1/(x^2) }}}, where the LCD= {{{4x^2}}}

{{{ (3/(4x))*(x/x) +(5/(x^2))*(4/4) + (1/(x^2))*(4/4) }}}

{{{ ((3x)/(4x^2)) + 20/(4x^2) + 4/(4x^2) }}}

{{{ (3x+24)/(4x^2)}}}
