Questions: A tile company adds 10% spoilage when estimating floors. We have a floor that is 34 feet by 30 feet and we want to know about what the company is going to buy to account for the spoilage. We estimate the dimensions of the room to the nearest tens and then the 10% spoilage. sq. ft. spoilage. I don't know

Solution Steps

The given dimensions of the floor are 34 feet by 30 feet. We need to round these dimensions to the nearest tens.

• 34 feet rounds to 30 feet.
• 30 feet rounds to 30 feet.

Thus, the estimated dimensions of the room are 30 feet by 30 feet.

Using the estimated dimensions, calculate the area of the room:

\[ \text{Area} = \text{length} \times \text{width} = 30 \, \text{ft} \times 30 \, \text{ft} = 900 \, \text{sq. ft} \]

The company adds a 10% spoilage to the estimated area. Calculate the spoilage:

\[ \text{Spoilage} = 0.10 \times 900 \, \text{sq. ft} = 90 \, \text{sq. ft} \]
