Question 524336
please help me with this. I am not good with word problems.
The diagonal of a square measures 4 inches What is the length of the sides?
--------------
Why do you call that a "word problem?"
---------
{{{d^2 = s^2 + s^2 = 2s^2}}}
{{{s^2 = d^2/2}}}
{{{s = sqrt(d^2/2) = d/sqrt(2) = d*sqrt(2)/2}}}
{{{s = 2sqrt(2)}}}
s =~ 2.828 inches
-------------------
Simpler:
{{{d^2 = s^2 + s^2 = 2s^2}}}
{{{s^2 = d^2/2 = 8}}}
{{{s = sqrt(8)}}}
