Answer:

72 units

Step-by-step explanation:

There are two ways to solve the problems.

Count graphically, horizontally there are 9 units, vertically there are 8 units in the rectangle.  So the area is 9*8 = 72 units.

Alternatively, check the difference between two adjacent vertices,

1. between (4,-3) and (4,5), the difference is (0,8), or 8 units.

2. between (4,5) and (-5,5), the difference is (9,0), or 9 units.

So again, the area of the square is 8*9=72 units.

Natalija [7]

Step-by-step explanation:

1. The first is a tabulation of the data, in an organized, clear and concise way for each event.

2. After tabulation, for a better understanding of the data, statistical data, such as the mean, median, and standard deviation of each event, should be collected.

3. Finally, graph the data obtained to see the trend of both cases and thus have a very precise way to make the comparison of both events
