Final answer:
The total area of the hotel lobby floor is 600 square feet. The hotel will spend $1050 on new carpet.
Step-by-step explanation:
To find the total area of the hotel lobby floor, we need to determine the dimensions of the floor and then multiply the length and width together.
If we have the measurements in feet, we can simply multiply the length and width. Let's say the length of the floor is 30 feet and the width is 20 feet. The total area would be 30 feet x 20 feet = 600 square feet.
To find out how much the hotel will spend on new carpet, we need to multiply the total area of the floor by the cost per square foot. If the new carpet costs $1.75 per square foot and the total area is 600 square feet, the hotel will spend $1.75 x 600 = $1050 on new carpet.
