Question 830096
Question:
If the area of a square is 144 {{{cm^2}}} ,find the length of its diagonal.
-------------------------------------------------
Answer:
The diagonal of a square is {{{sqrt(2)}}} times longer than its side.
{{{A = s^2}}}, where A = area and s = side
{{{s^2 = 144}}}
{{{s = sqrt(144) = 12}}}
Therefore, diagonal = {{{highlight(12sqrt(2) cm)}}}
