\n" ); document.write( " the length of the first side of a triangle piece of wood is twice the length of the second side and the length of the third side is one inch less than the first side if the perimeter is 79 what are the lengths of the sides ? \r
\n" ); document.write( "\n" ); document.write( " Let the length of the second side = x inch
\n" ); document.write( " the length of the first side = 2x inch
\n" ); document.write( " the length of the third side = 2x-1 inch
\n" ); document.write( " the perimeter of the triangle = 79 inch
\n" ); document.write( " perimeter = sum of all the three sides of the triangle
\n" ); document.write( " p = first+second+three
\n" ); document.write( " 79 = x+2x+(2x-1)
\n" ); document.write( " 79+1 = 5x 5x = 80
\n" ); document.write( " x= 80/5 = 16
\n" ); document.write( " first side = 2.16 = 32 inch
\n" ); document.write( " second side = 16 inch
\n" ); document.write( " third side = 31 inch \n" ); document.write( "
