Step-by-step explanation:
The question is incomplete as the matrix is not given.
The general form of a matrix is:
![b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right]](https://tex.z-dn.net/?f=b%5Bm%2An%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Db_%7B11%7D%26b_%7B12%7D%26b_%7B13%7D........b%7B1n%7D%7D%5C%5Cb_%7B21%7D%26b_%7B22%7D%26b_%7B23%7D........b%7B2n%7D%5C%5Cb_%7B31%7D%26b_%7B32%7D%26b_%7B33%7D........b%7B3n%7D%5C%5C%20%5C%5C%20%5C%5Cb_%7Bm1%7D%26b_%7Bm2%7D%26b_%7Bm3%7D........b%7Bmn%7D%5Cend%7Barray%7D%5Cright%5D)
Where m and n represent the
respectively.
Notice the position of b11
This means that b11 is at the first column and first row.
Take for instance matrix b is:
![b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]](https://tex.z-dn.net/?f=b%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%263%5C%5C4%265%266%5C%5C7%268%269%5Cend%7Barray%7D%5Cright%5D)
The element at the first row and first column is 1.
Hence

If you multiply 6 3/4 by 16, you get 108, which is how much rope he has in general. If he were to divide this length by 20 for 20 people, that would be 5.4, so each person would get 5.4 meters of rope.
