trapezoid jklm in the x - y plane has coordinates j = ( – 2 , – 1 ) , k = ( – 2 , 1 ) , l = ( 6 , 7 ) , and m = ( 6 , – 1 ) . what is its perimeter ?
"jk = 2 lm = 11 kl = using distance formula 10 jm = using distance formula 8 sum of all is 31 c"
add(add(add(const_10, add(1, 1)), add(2, 6)), add(7, 1))
