Let
\n" ); document.write( "L be the length
\n" ); document.write( "W be the width\r
\n" ); document.write( "\n" ); document.write( "Suppose
\n" ); document.write( "L=3w\r
\n" ); document.write( "\n" ); document.write( "Our formula for finding the area is L multiplied by the width (A=L*W).
\n" ); document.write( "So, firstly we substitute the value of L\r
\n" ); document.write( "\n" ); document.write( " $\"3w%2Aw=6.75\"$
\n" ); document.write( " $\"3w%5E2=6.75\"$ \r
\n" ); document.write( "\n" ); document.write( "Apply division property to isolate $\"w%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3w%5E2%2F3=6.75%2F3\"$
\n" ); document.write( " $\"w%5E2=2.25\"$ \r
\n" ); document.write( "\n" ); document.write( "Square root both sides\r
\n" ); document.write( "\n" ); document.write( " $\"sqrt%28w%5E2%29=sqrt%282.25%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Where w=1.5\r
\n" ); document.write( "\n" ); document.write( "If w is 1.5 then length is 3 times its width which is equal to 4.5\r
\n" ); document.write( "\n" ); document.write( "Check\r
\n" ); document.write( "\n" ); document.write( "1.5 * 4.5
\n" ); document.write( "=6.75\r
\n" ); document.write( "\n" ); document.write( "Therefore our width is 1.5 m and length is 4.5m\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
