To determine the number of rectangles that can be made using 24 tiles, we need to consider the different possible dimensions of rectangles. A rectangle can have a length and width ranging from 1 to 24, inclusive. Each unique combination of length and width will form a distinct rectangle, so the total number of rectangles can be calculated by summing the total number of combinations for each possible length and width. This can be done using the formula n(n+1)/2 for the sum of the first n natural numbers, where n is the total number of tiles (24 in this case).

Make 4 equally spaced columns of 3 matchsticks. Across the top put the first row of 3 matchsticks and then put a further two rows of matchsticks equally spaced. This will form 9 small equal squares within a larger square.
