The shape of a wall in a museum is shown to the 28 right, where heights (in feet) are given at 6-foot 26 26 28 27.5 intervals. The wall is to be paneled, and the cost to 24 25 22 panel each square foot is $4 50. Find the approximate cost of paneling the wall 6 ft Which of the following sums would give the best approximation for the area of the wall? O Rn= 6 7+2h2+2h3 + 2h4 + 25 + 2h6 + 2h7 + 2 O In = 6 7 + 12 + hg + ha + hs +h6+ h7 + 2) O Tn = 2 7+ 212 + 2hg + 2h + 215 +2h6 + 2h7 + 2 O Rn = 6 (h2 +hy + haths +h6 + hy+hy) The approximate cost of paneling the wall is $
