You can put this solution on YOUR website!
the formulae for the area of a triangle: (b*h)/2 with b=base and h=height
\n" ); document.write( "In your excercise we have: height = 2 * base or h = 2 * b
\n" ); document.write( "Putting this in the area-formulae: (b * 2 * b)/2 = (2*bē)/2 = bē
\n" ); document.write( "And this has to be 49: bē= 49
\n" ); document.write( "or b = sqrt(49) = 7\r
\n" ); document.write( "\n" ); document.write( "greets \n" ); document.write( "
