The whole length of wire is \"+5+\" ft
\n" ); document.write( "\"+x+\" ft is used for the equilateral triangle
\n" ); document.write( "\"+5+-+x+\" is used for the circle
\n" ); document.write( "-----------------
\n" ); document.write( "The area of the triangle is \"A+=++%281%2F2%29%2Ab%2Ah+\"
\n" ); document.write( "The base is \"+x%2F3+\" . The height is \"+%281%2F2%29%2A%28x%2F3%29%2Asqrt%283%29+\"
\n" ); document.write( "\"+A+=+%281%2F2%29%2A%28x%2F3%29%2A%28x%2F6%29%2Asqrt%283%29+\"
\n" ); document.write( "\"+A+=+%28+x%2Asqrt%283%29%29+%2F+36+\"
\n" ); document.write( "----------------------
\n" ); document.write( "The area of the circle is \"+pi%2Ar%5E2+\"
\n" ); document.write( "To find \"r\", find the circumference
\n" ); document.write( "\"+C+=+2%2Api%2Ar+\"
\n" ); document.write( "\"+5+-+x+=+2%2Api%2Ar+\"
\n" ); document.write( "\"+r+=+%28+5+-+x+%29+%2F+%282%2Api%29+\"
\n" ); document.write( "and
\n" ); document.write( "\"+A+=+pi%2A%285+-+x%29%5E2+%2F+%28+4%2Api%5E2+%29+\"
\n" ); document.write( "\"+A+=+%281%2F%284%2Api%29%29%2A%28+25+-+10x+%2B+x%5E2+%29+\"
\n" ); document.write( "Hope I got it\r
