If the measure of the side of a square is decreased by 3cm, its perimeter is 48cm.
\n" ); document.write( " What is the measure of its side?
\n" ); document.write( ":
\n" ); document.write( "Let x = the side of the square
\n" ); document.write( "then
\n" ); document.write( "(x-3) = the decreased side
\n" ); document.write( "and
\n" ); document.write( "4(x-3) = 48; the decreased square perimeter
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "x - 3 = 48/4
\n" ); document.write( "x - 3 = 12
\n" ); document.write( "x = 12 + 3
\n" ); document.write( "x = 15 is the measure of it's side \n" ); document.write( "
\n" );
