Question 980672
The painting is square of x for both width and length.


{{{x^2}}}, the area of just the painting
{{{(x+2*3)(x+2*3)}}}, the area of frame and the painting


{{{highlight_green((x+6)^2=961)}}}------Solve this equation.


{{{x^2+12x-925=0}}}
{{{(x-25)(x+37)=0}}}
{{{highlight(x=25)}}}, because it is a meaningful, POSITIVE value.
