Final answer:
The expression 11(7+4) calculates the total area of the first floor of a tiny house by multiplying the length (11 feet) by the combined width of the kitchen and the bathroom (7+4 feet), resulting in 121 square feet.
Step-by-step explanation:
The expression 11(7+4) represents the total area in square feet of the first floor of a tiny house when multiplied together. The length of the first floor is 11 feet, and the combined width of the kitchen and bathroom floor is 7 feet + 4 feet, respectively. Therefore, the area of the first floor of the house can be calculated by multiplying the length by the total width.
To find the total area, you perform the operation inside the parentheses first, which is the sum of the widths of the kitchen and bathroom:
- 7 feet (kitchen width) + 4 feet (bathroom width) = 11 feet (total width)
Then, you multiply this sum by the length of the house to get the area:
- 11 feet (length) × 11 feet (total width) = 121 square feet (total area)
Thus, the total area of the first floor of this tiny house is 121 square feet.
