Question 957643
The diagonal of a rectangle forms a right triangle with the length and width.
a=length=12in; b=width=7in; c=diagonal
{{{a^2+b^2=c^2}}}
{{{(12in)^2+(7in)^2=c^2}}}
{{{144in^2+49in^2=c^2}}}
{{{193in^2=c^2}}} Find the square root of each side.
{{{13.89in=c}}} ANSWER: The diagonal is 13.89 inches.
