b. If Cecelia's bedroom is 12 feet by 15.5 feet, what is the area of the bedroom floor? Show how you got your answer.

[tex]\[ \text{Area} = \text{length} \times \text{width} = 12 \times 15.5 = 186 \text{ square feet} \][/tex]

c. Find the perimeter of Cecelia's bedroom floor. Show how you got your answer.

Sure! Let's find the area and the perimeter of Cecelia's bedroom:

b. To find the area of the bedroom floor:
1. Dimensions: Cecelia's bedroom is 12 feet long and 15.5 feet wide.
2. Formula for Area: The area of a rectangle is calculated by multiplying the length by the width.
3. Calculation:
- Area = length × width
- Area = 12 feet × 15.5 feet
- Area = 186 square feet

So, the area of Cecelia's bedroom floor is 186 square feet.

c. To find the perimeter of the bedroom floor:
1. Formula for Perimeter: The perimeter of a rectangle is calculated by adding up the lengths of all four sides. Since a rectangle has two pairs of equal sides, you can use the formula:
- Perimeter = 2 × (length + width)
2. Calculation:
- Perimeter = 2 × (12 feet + 15.5 feet)
- Perimeter = 2 × 27.5 feet
- Perimeter = 55 feet

So, the perimeter of Cecelia's bedroom floor is 55 feet.
