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. \n" ); document.write( " |
