The height of a right angled triangle is twice as long as its base. If the area is 30cm^2, find the length of the base.
\n" ); document.write( "---------------
\n" ); document.write( "Area = b*h/2 = 30
\n" ); document.write( "h = 2b
\n" ); document.write( "=============
\n" ); document.write( "b = sqrt(30)
\n" ); document.write( "h = 2sqrt(30)
\n" ); document.write( "
\n" ); document.write( "
