You can put this solution on YOUR website!
area of triangle = (1/2)*b*h where b is the length of base and h is the height
\n" ); document.write( "area is given to be x^2 +5x + 6
\n" ); document.write( "height = x+3\r
\n" ); document.write( "\n" ); document.write( "1/2*b*(x+3) = x^2 + 5x + 6\r
\n" ); document.write( "\n" ); document.write( "The right side x^2 +5x + 6 can be factorised as (x+3)(x+2)\r
\n" ); document.write( "\n" ); document.write( "(1/2)*b*(x+3) = (x+3)(x+2)\r
\n" ); document.write( "\n" ); document.write( "cancelling (x+3) on both sides leaves
\n" ); document.write( "(1/2)*b = x+2
\n" ); document.write( "b = 2*(x+2) = 2x+4
\n" ); document.write( "The length of the base is 2x+4\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
