Final answer:
To find the factors of 30 using tiles on grid paper, draw a rectangle with dimensions of 30 tiles by 1 tile. The number of rows and columns will represent the factors. In this case, the factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
Step-by-step explanation:
To find the factors of 30, you can use tiles on grid paper. Start by drawing a rectangle on the grid paper with a length of 30 tiles and a width of 1 tile. Then, count the number of rows and columns to find the factors. In this case, the factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
