Explanation:

Question 7 (Assuming the rectangle from the perimeter question has length 10 ft and width 5 ft, as perimeter options suggest a rectangle with sides that make sense for perimeter calculation. Let's assume length \( l = 10 \) ft and width \( w = 5 \) ft from the perimeter context)

Step 1: Recall the formula for the area of a rectangle

The formula for the area \( A \) of a rectangle is \( A = l \times w \), where \( l \) is the length and \( w \) is the width.

Step 2: Substitute the values of length and width

Given (from perimeter context, assuming) \( l = 10 \) ft and \( w = 5 \) ft. So, \( A = 10 \times 5 \).

Step 3: Calculate the product

\( 10 \times 5 = 50 \) square feet.

Step 1: Understand the conversion factor

We know that 1 inch = 2.5 centimeters. We need to find the length in centimeters for 8 inches.

Step 2: Set up the multiplication

To find the length in centimeters for 8 inches, we multiply the number of inches (8) by the conversion factor (2.5 cm per inch). So, the calculation is \( 8 \times 2.5 \).

Step 3: Perform the multiplication

\( 8 \times 2.5 = 20 \).

Step 1: Recall the formula for division to find the number of times

To find how many times the area of Rhode Island (1214 square miles) fits into Texas (266,807 square miles), we divide the area of Texas by the area of Rhode Island. So, the formula is \( \text{Number of states} = \frac{\text{Area of Texas}}{\text{Area of Rhode Island}} \).

Step 2: Substitute the values

Substitute the values: \( \frac{266807}{1214} \).

Step 3: Perform the division (approximate)

\( \frac{266807}{1214} \approx 219.8 \), which is approximately 219.

Answer:

b) 50 square feet
