Let's solve this problem step-by-step, keeping in mind that we're trying to find the total length of fabric needed to make curtains for a living room window.
1. Identify the lengths of each piece of fabric needed:
- Piece 1: 3 feet
- Piece 2: 3 feet
- Piece 3: 5 feet
2. Calculate the total length of fabric by summing these individual lengths:
- Total length = Length of Piece 1 + Length of Piece 2 + Length of Piece 3
- Total length = 3 feet + 3 feet + 5 feet
3. Add these values together:
- Total length = 3 + 3 + 5
4. Find the sum:
- Total length = 11 feet
Therefore, the total length of fabric you will need is 11 feet.
The correct answer is B. 11 feet.
