Area of triangle = (base * height)/2\r
\n" ); document.write( "\n" ); document.write( "We have been given\r
\n" ); document.write( "\n" ); document.write( "Area of triangle = 8.4 sq m
\n" ); document.write( "height = 4.8 m
\n" ); document.write( "base = ?\r
\n" ); document.write( "\n" ); document.write( "a = (b*h)/2
\n" ); document.write( "Multiply by 2 both sides
\n" ); document.write( "2a = bh
\n" ); document.write( "2a/h = bh/h
\n" ); document.write( "2a/h=b
\n" ); document.write( "b=2a/h
\n" ); document.write( "Plug in the values of a, h in above equation\r
\n" ); document.write( "\n" ); document.write( "b = 2*(8.4) / 4.8
\n" ); document.write( "b = 16.8/4.8
\n" ); document.write( "b = 3.5 m\r
\n" ); document.write( "\n" ); document.write( "Length of base is 3.5 meter.
\n" ); document.write( "
\n" );
