A grid is made up of columns and rows and the product of the number of rows and the number of columns result in the total number of items in the grid.
In this case, Total number of trees = (Number of rows × Number of columns).
Let us assume that the number of columns is “

x

”. Then, we will form a linear equation with x based on the formula mentioned just above with the data provided from the question, and solving this equation for x, we will obtain our desired answer.
