You can put this solution on YOUR website!
Let \"s\"= 2 equal sides, and \"b' = base
\n" ); document.write( "Since the sides are 6cm longer than the base, \"s= b+6\"
\n" ); document.write( "For the perimeter, we get the measurements of 2 equal sides + the base,
\n" ); document.write( " $\"P=+2s+%2B+b+\"$
\n" ); document.write( " $\"45cm+=+2%28b%2B6%29+%2B+b\"$
\n" ); document.write( " $\"45+=+2b+%2B+12+%2B+b\"$
\n" ); document.write( " $\"45+-+12+=+3b\"$
\n" ); document.write( " $\"%2833%2F3%29+=+b\"$ ----------- > $\"b=+11cm\"$ , base of the triangle
\n" ); document.write( "FYI, the sides will be $\"s=+11+%2B+6\"$ ----> $\"s=+17+cm\"$ , 2 equal sides
\n" ); document.write( "To check,
\n" ); document.write( " $\"P=+2s+%2B+b\"$
\n" ); document.write( " $\"+45cm+=+%282%2A17%29+%2B+11+\"$
\n" ); document.write( " $\"45cm+=+34+%2B+11+\"$
\n" ); document.write( " $\"45cm+=+45cm\"$
