The length of a rectangle is 4 cm less that three times its width. If the length is increased by 8 cm and the width is decreased by 2 cm, the perimeter will be 100 cm. Find the dimensions of the orifinal rectangle.
\n" ); document.write( "---------------
\n" ); document.write( "Old Dimensions:
\n" ); document.write( "width=x
\n" ); document.write( "length = 3x-4
\n" ); document.write( "------------------
\n" ); document.write( "New Dimensions:
\n" ); document.write( "width = x-2
\n" ); document.write( "length = 3x-4+8=3x+4
\n" ); document.write( "---------
\n" ); document.write( "EQUATIOn:
\n" ); document.write( "Using new dimensions 2(length + width) = 100 cm
\n" ); document.write( "2(x-2+3x+4)=100
\n" ); document.write( "4x+2=50
\n" ); document.write( "4x=48
\n" ); document.write( "x=12
\n" ); document.write( "---------
\n" ); document.write( "Old width was 12 cm
\n" ); document.write( "Old length was 3(12)-4=32 cm
