Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.
