W=width L=length=3W
\n" ); document.write( "A=L x W =144 sq m
\n" ); document.write( "(3W)(W)=144 sq m
\n" ); document.write( " $\"3W%5E2=144+sqs+m\"$ divide each sidde by 3
\n" ); document.write( " $\"3w%5E2%2F3=144%2F3\"$
\n" ); document.write( " $\"w%5E2=48+sq+m\"$ find Square root of each side
\n" ); document.write( " $\"sqrt%28W%5E2%29=+sqrt%2848+sqm%29\"$
\n" ); document.write( " $\"W=4%2Asqrt%283%29\"$
\n" ); document.write( "CHECK
\n" ); document.write( "A=L x W=3W x W
\n" ); document.write( " $\"144+sq+m=3%284%2Asqrt%283%29%29%2A4%2Asqrt%283%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+144+sq+m=48%28sqrt%283%29%5E2%29\"$
\n" ); document.write( "144 sq m=48(3)sq m
\n" ); document.write( "144 sq m= 144 sq m
\n" ); document.write( " \n" ); document.write( "
