Find area under curve of every n rows

Hi. I have a 648 x 14 matrix. I want to calculated the area under the curve of every 24 values created by the values in column 5. I can do this within a loop but I want to perform the same function on different matrices with a varying number of rows. Is it possible to do this without a loop

for i = 1:27
    area(i,1) = trapz(MAM10(24*i-23:24*i,5));
end

trapz( reshape(MAM10(:,5), 24, []) )
