Question 1065940
Doing #3 only


x, the side length of the square
x+4 is the width for the rectangle, and 2+(x+4) is the length of the rectangle.


Combined Area:
{{{x^2+(x+4)(x+6)=124}}}


STEPS

{{{x^2+x^2+10x+24=124}}}
{{{2x^2+10x-100=0}}}
{{{x^2+5x-50=0}}}
{{{(x-5)(x+10)=0}}}
This will mean that {{{highlight(x=5)}}}, side length of the square.


Evaluate the rectangle's x+4 and x+6.
