Let p = the perimeter of the triangle
\n" ); document.write( "Since the perimeter is the sum of the three side we get from the problem statement,
\n" ); document.write( "(1) p = 5 + (3/7)*p + (1/2)*p or
\n" ); document.write( "(2) p*(1 - (3/7) - (1/2)) = 5 or
\n" ); document.write( "(3) p*(14 - 7 -6) = 14*5 or
\n" ); document.write( "(4) p = 70
\n" ); document.write( "Let's check this using (1),
\n" ); document.write( "Is (70 = 5 + (3/7)*70 + (1/2)*70)?
\n" ); document.write( "Is (70 = 5 + 30 + 35)?
\n" ); document.write( "Is (70 = 70)? Yes
\n" ); document.write( "Answer: The perimeter of the triangle is 70 cm.
