The 2 sides have an area:

\n" ); document.write( "The top and bottom add up to:
\n" ); document.write( " $\"+2%2A2%2A.5+=+2+\"$ m2
\n" ); document.write( "The total area adds up to:
\n" ); document.write( " $\"+3+%2B+2+=+5+\"$ m2
\n" ); document.write( "----------------------
\n" ); document.write( "The cost of these materials is:
\n" ); document.write( " $\"+5%2A3+=+15+\"$
\n" ); document.write( "$15
\n" ); document.write( "The best estimate may include some waste
