Length of the rectangle exceeds its breadth by 7cm.
\n" ); document.write( " if the length is decreased by 4cm.
\n" ); document.write( " the area of the new rectangle is same as area of the original rectangle.
\n" ); document.write( "find the length of original rectangle.
\n" ); document.write( ":
\n" ); document.write( "This does not seem possible, but assume it is
\n" ); document.write( ":
\n" ); document.write( "Let x = the width
\n" ); document.write( "then
\n" ); document.write( "(x+7) = the length
\n" ); document.write( "and
\n" ); document.write( "x(x+7) = the area
\n" ); document.write( ":
\n" ); document.write( "\"if the length is decreased by 4cm. the area of the new rectangle is same as area of the original rectangle.\"
\n" ); document.write( "x(x+3) = the new area
\n" ); document.write( "therefore
\n" ); document.write( "x(x+7) = x(x+3)
\n" ); document.write( "divide both sides by x
\n" ); document.write( "x + 7 = x + 3; no sense here
\n" ); document.write( " \n" ); document.write( "
\n" );
