I see that you've uploaded an image with three mathematical problems. I'll interpret the image and help solve each one.

### Problem 1: 
**"Trevor is using pulleys and arrows to apply a spring in the direction of the arrow. The coil of spring can be stretched to an area of 10 square feet. Does Trevor have enough spring space for this arrow?"**
- Dimensions of the arrow: 2 ft (height) by 5 ft (width).

**Solution**:  
The area of the arrow can be calculated as a simple rectangle since there are no other shapes involved. The formula for the area of a rectangle is:

\[
\text{Area} = \text{length} \times \text{width}
\]

Here, the dimensions are 5 ft by 2 ft.

\[
\text{Area} = 5 \times 2 = 10 \text{ square feet}
\]

Since the spring can stretch to 10 square feet, Trevor has enough space for the spring.

### Problem 2: 
**"Determine the area of the shaded trapezoid."**
- Dimensions: 
  - Top base = 4 inches
  - Bottom base = 8 inches
  - Height = 3 inches

**Solution**:  
The area of a trapezoid is calculated using the formula:

\[
\text{Area} = \frac{1}{2} \times (\text{Base}_1 + \text{Base}_2) \times \text{Height}
\]

Substituting the values:

\[
\text{Area} = \frac{1}{2} \times (4 + 8) \times 3 = \frac{1}{2} \times 12 \times 3 = 18 \text{ square inches}
\]

So, the area of the shaded trapezoid is **18 square inches**.

### Problem 3: 
**"Eight triangles are drawn within a square to create the shaded region in the figure."**
- The large square has a side length of 10 cm.
- Each of the four small triangles within the square is made by cutting out squares from the corners.

**Solution**:  
1. First, calculate the area of the entire large square:

\[
\text{Area of large square} = \text{side}^2 = 10^2 = 100 \text{ square centimeters}
\]

2. The four corner squares are right triangles with legs measuring 3 cm. The area of one right triangle is:

\[
\text{Area of one triangle} = \frac{1}{2} \times 3 \times 3 = 4.5 \text{ square centimeters}
\]

Since there are 4 triangles, the total area removed is:

\[
\text{Total area of triangles} = 4 \times 4.5 = 18 \text{ square centimeters}
\]

3. Subtracting the area of the triangles from the area of the large square gives the shaded area:

\[
\text{Shaded area} = 100 - 18 = 82 \text{ square centimeters}
\]

1. How would the solution change if the spring stretched to only 8 square feet in Problem 1?
2. What happens to the area of the trapezoid if the height is doubled?
