Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered t

Answer:

a. Perry covered more ground

b. Karina covered an area of 9 square units

Perry covered a region measuring 18 square units

Step-by-step explanation:

Here, we need to validate our conclusion through mathematical reasoning.

Initially, we determine who has managed to cover the greater area.

The most effective way to approach this is by examining the dimensions of the areas they have each cleaned.

Karina has a square with sides of 3 units by 3 units

Whereas Perry has a rectangle that measures 9 units by 2 units

We recognize that by comparing the areas, a square of 3 by 3 has a lesser area compared to a rectangle with dimensions of 9 by 2

Consequently, since the rectangle covers a larger area, it is Perry who has accomplished more in her community service

For area calculations;

For Karina:

3 by 3 = 3 units * 3 units = 9 square units

For Perry, the calculation is

9 by 2 = 9 units * 2 units = 18 square units
