he sides of a triangle are in the ratio 3:4:5.
\n" ); document.write( " what is the length of each side if the perimeter is 30cm?
\n" ); document.write( ":
\n" ); document.write( "let x = the multiplier
\n" ); document.write( "then
\n" ); document.write( "3x + 4x + 5x = 30
\n" ); document.write( "12x = 30
\n" ); document.write( "x = 30/12
\n" ); document.write( "x = 2.5 if the multiplier, therefore the three sides are:
\n" ); document.write( "3*2.5 = 7.5
\n" ); document.write( "4*2.5 = 10
\n" ); document.write( "5*2.5 = 12.5
\n" ); document.write( "
\n" );
