To set up the blocks in an array with the same number of rows and columns, Jason could use a square number of blocks, as square numbers have equal rows and columns. Examples of square numbers between 20 and 90 include 25, 36, 49, 64, and 81.
Jason could use a grid paper or a computer program like Microsoft Excel to set up the blocks in an array. He can create rows and columns in the program corresponding to the square number of blocks he chooses, and then place the blocks in each cell of the array. Using a grid paper or a computer program will help Jason visually organize and arrange the blocks in the desired array structure.
