#### 4. Ronnie wants to buy a computer table that measured 10 feet by 17 feet. The cost of the table is $17 per square foot. How much will it cost Ronnie to buy the computer table for his study room?

- Step 1: Calculate the area of the computer table.
\[
\text{Area} = \text{Length} \times \text{Width}
\]
- Given:
- Length = 10 feet
- Width = 17 feet
\[
\text{Area} = 10 \times 17 = 170 \text{ square feet}
\]

- Step 2: Calculate the total cost.
- Cost per square foot = $17
\[
\text{Total Cost} = \text{Area} \times \text{Cost per Square Foot}
\]
\[
\text{Total Cost} = 170 \times 17 = 2890
\]

#### 6. Diane knows that the area of her square shaped bag is 81 feet². What is the length of any side of the bag?

- Formula for Area of a Square:
\[
\text{Area} = \text{Side}^2
\]

- Given:
- Area = 81 feet²

- Step 1: Solve for the side length.
\[
\text{Side} = \sqrt{\text{Area}}
\]
\[
\text{Side} = \sqrt{81} = 9 \text{ feet}
\]

- Answer:
\[
\boxed{9 \text{ feet}}
\]
