Question 161245
</pre><font size=4><b>
Remember: {{{P[T]=a+b+c}}} ----------------------> EQN 1
where {{{a=longest=highlight(x(yards))}}}
{{{b=2ndlongest=highlight(x-2(yards))}}}
{{{c=shortest=highlight((1/2)x+30(yards))}}}
{{{P=378 yards}}}
Going back EQN 1,
{{{378=x+x-2+(1/2)x+30}}}
{{{378=2(1/2)x+28}}}
{{{378-28=2(1/2)x}}}
{{{350=2(1/2)x}}}
{{{cross(350)140/cross(2(1/2))=cross(2(1/2))x/cross(2(1/2))}}}
{{{x=140yards}}} LONGEST side (a)
{{{140-2=138yards}}} 2ND LONGEST (b)
{{{(1/2)(140)+30=70+30=100yards}}} SHORTEST (c)
Check via EQN 1:
{{{378=140+138+100}}}
{{{378yards=378yards}}}
Thank you,
