Question 1117614
{{{x(x+14)=112}}}


You can use algebra to solve the quadratic equation.


You can also look at which factors of 112, if any differ by 14.



{{{112=4*28=8*14}}}
{{{112=2*56}}}
{{{112=7*16}}}


-

{{{x^2+14x-112=0}}}
-


{{{x=(-14+sqrt(196+4*112))/2}}}

{{{x=(-14+sqrt(644))/2}}}

{{{x=(-14+2*sqrt(161))/2}}}

{{{x=-7+sqrt(161)}}}------width


length, {{{7+sqrt(161)}}}
