\n" );

document.write( "So i know that I am trying to find the length so that obviously is my x. Then i also know that the width is 4m less than that, but i get so thrown off by the 12 squared that i can't figure out how to set up the problem :/ \n" );

Algebra.Com's Answer #188909 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! What is the area ? length times width. \n" ); document.write( "You actually don't say what we are looking for. Are we looking for the width, length or both? \n" ); document.write( "I will use A for area L for length and W for width \n" ); document.write( "L*W=A \n" ); document.write( "L*W=12 \n" ); document.write( "W=L-4 \n" ); document.write( "L*(L-4)=12 \n" ); document.write( "L^2-4L-12=0 \n" ); document.write( "(L-6)(L+2)=0 \n" ); document.write( "L=6 meters \n" ); document.write( "W=L-4=2 meters \n" ); document.write( " |
