Question 292741
It is telling you that {{{90}}} ft is one
side of the square, and it is asking you
for the distance between opposite corners.
The sides are all equal to {{{90}}} ft
and, for a square, the diagonal and a side
are in the ratio {{{sqrt(2)}}} to {{{1}}},
so I can say {{{sqrt(2)/1 = x/90}}}
Multiply both sides by {{{90}}}
{{{90*sqrt(2) = x}}}
{{{x = 1.414*90}}}
{{{x = 127.3}}} ft (rounded to nearest 1/10 th)
