Answer 1

To represent an 8 row by 7 column rectangular block in an array would result in an area of 56 cells or 56 square meters.

Step-by-step explanation:

To build a rectangular block with a user-entered number of rows and columns, you'll need a nested for loop structure in a programming language. However, based on the question's additional criteria about calculating the area and expressing it as an area in meters, it seems like we're also dealing with a mathematics concept here.

If a user enters 8 rows and 7 columns, the array (or grid) for the rectangular block will be 8x7. This means the array will have a total of 56 cells (1 row of 7 columns times 8 such rows). If we are to express this as an area in meters, assuming each cell is 1 meter squared, then the area would also be 56 square meters.

Furthermore, if you want to express this area as a side length for a square of the same area, you would take the square root of the area. Since the area is 56 square meters, the side length of a square with the same area would be √56, which is approximately 7.48 meters for each side.
