You can put this solution on YOUR website!
We have the area of the garden is 3 * 7 = 21 sq m., if the area of the walk is 11 the total area is 32 sq. m\r
\n" ); document.write( "\n" ); document.write( "(7 + x)(3 + x) = 32 sq. meters.\r
\n" ); document.write( "\n" ); document.write( "x^2 + 10x + 21 = 32\r
\n" ); document.write( "\n" ); document.write( "x*2 + 10x -11 = 0\r
\n" ); document.write( "\n" ); document.write( "(x + 11)(x - 1) = 0\r
\n" ); document.write( "\n" ); document.write( "x = 1\r
\n" ); document.write( "\n" ); document.write( "To check, 4 * 8 = 32 sq m.
\n" ); document.write( " We can see this does check.
