338=b*h where h=3b-13
\n" ); document.write( "338=b(3b-13)
\n" ); document.write( "338=3b^2-13b
\n" ); document.write( "3b^2-13b-338=0
\n" ); document.write( "(3b+26)(b-13)=0
\n" ); document.write( "b-13=0
\n" ); document.write( "b=13 answer for the base.
\n" ); document.write( "h=3*13-13
\n" ); document.write( "h=39-13
\n" ); document.write( "h=26 answer for the height.
\n" ); document.write( "perimeter=2*b+2*h
\n" ); document.write( "p=2*13+2*26
\n" ); document.write( "p=26+52
\n" ); document.write( "p=78 answer for the perimeter.\r
