For the triangular sides, the area of one side is:
\n" ); document.write( "\"A+=+%281%2F2%29bh\" The base (b) is given as 10 feet and the height (h) is given as 10 feet. So...
\n" ); document.write( "\"A+=+%281%2F2%29%2810%29%2810%29\"
\n" ); document.write( "\"A+=+50\" square feet for one of the four triangular sides.
\n" ); document.write( "The four sides would have an area that is four times this or 4 X 50 = 200 square feet.
\n" ); document.write( "For the base,the area would be:
\n" ); document.write( "\"A+=+L%2AW\" The length (L) and width (W) are given as 10 feet each, so...
\n" ); document.write( "\"A+=+%2810%29%2810%29\"
\n" ); document.write( "\"A+=+100\"square feet.
\n" ); document.write( "The total area is the sum of all of these:
\n" ); document.write( "\"A%5Bt%5D+=+200%2B100\"
\n" ); document.write( "\"A%5Bt%5D+=+300\"square feet.
\n" ); document.write( "
\n" );
