VARIABLES:
\n" ); document.write( "let the width of the rectangle = x\r
\n" ); document.write( "\n" ); document.write( "let length= 4+2x\r
\n" ); document.write( "\n" ); document.write( "since you are finding the perimeter of the rectangle, the formula is \r
\n" ); document.write( "\n" ); document.write( "length + length + width + width = perimeter ==> 2(length)+2(width)= perimeter\r
\n" ); document.write( "\n" ); document.write( "plug in variables for length and width.
\n" ); document.write( " 2x+2(4+2x)=62
\n" ); document.write( " 2x+8+4x=62
\n" ); document.write( " 6x+8=62 (subtract 8 from both sides)
\n" ); document.write( " 6x=54 (divide doth sides by 6)
\n" ); document.write( " x=9
\n" ); document.write( "so the width is 9
\n" ); document.write( "length is 4+2x ==> 4+2(9) ==> 22
\n" ); document.write( "answer: width 9 length 22\r
\n" ); document.write( "\n" ); document.write( "check:
\n" ); document.write( "9+9+22+22=62
\n" ); document.write( "18+44=62
\n" ); document.write( "62=62
\n" ); document.write( " \n" ); document.write( "
\n" );
