Answer:
- Heather's model represents the greater area.
greater.
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght of the rectangle and "w" is the width.
The formula for calculate the area of a square is:
Where "s" is the side lenght.
In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:
Therefore, substituting these values into the formula , we get that the area is:
Since Heather's model represented 18 ft by 18 feet, we can identify that:
Substituting this value into , we get this area:
Notice that Heather's model represents the greater area.
To calculate how much greater it is, subtract the areas. Then:
