First, find the area of the triangle. \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=%28bh%29%2F2\" Start with the area of a triangle formula\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=%2830%2A20%29%2F2\" Plug in b=30 and h=20\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=600%2F2\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=300\" Divide\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the area of the triangle is 300 square feet.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now multiply the area of the rectangle by the cost per square foot to get: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"300%2A3=900\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So it will cost a total of $900 to cover the triangular front with glass.
\n" ); document.write( "
\n" );
