\n" ); document.write( "\n" ); document.write( "We can now know the base of the triangle is 4 units and the height of the triangle is 4 units.\r
\n" ); document.write( "\n" ); document.write( "To calculate the area of the triangle, use the formula of area of triangle = 1/2 x base x height\r
\n" ); document.write( "\n" ); document.write( "Therefore,
\n" ); document.write( "Area of Triangle = 1/2 x 4 x 4
\n" ); document.write( "Area of triangle = 8 units.
