a rectangle has a length that is 1m less than twice its width.
\n" ); document.write( "L = 2W-1
\n" ); document.write( ":
\n" ); document.write( "increasing the width by 3m and decreasing the length by 1m results in a square
\n" ); document.write( "Then the length and width will be equal; therefore:
\n" ); document.write( "L-1 = W+3
\n" ); document.write( "L = W + 3 + 1
\n" ); document.write( "L = W + 4
\n" ); document.write( "Replace L with (2W-1), find W
\n" ); document.write( "2W - 1 = W + 4
\n" ); document.write( "2W - W = 4 + 1
\n" ); document.write( "W = 5 units is the width
\n" ); document.write( "then
\n" ); document.write( "2(5) - 1 = 9 units is the length
\n" ); document.write( ":
\n" ); document.write( "find the dimensions of the rectangle. 9 by 5
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can check this by finding what the side of the square is
\n" ); document.write( "Subtract 1 from 9 and add 3 to 5 \n" ); document.write( "
\n" );
