Answer:
First you should remember that the formula for calculating area of a rectangle is;
Area=Length × width
You can decide to have a rectangle with different dimensions provided the area is 24 square unit
For this case, lets choose a rectangle with vertices at (1,0), (7,0),(1,4), (7,4)
After plotting these coordinates, you will notice your rectangle has a length of 6 units and a width of 4 units
A single unit is 1 square unit.When you Count the number of units inside the rectangle formed you realize you have 24 units covered inside
The area of the 24 units will be;
24×1 square unit= 24 square units
