To find the area of this shape, we need to break it down into simpler parts. The diagram shows a triangle on the right side with an adjacent rectangle to its left.

1. Area of the rectangle:

   • The dimensions of the rectangle are 17 feet (length) by 18 feet (height).
   • The area of the rectangle is calculated by multiplying its length and height: $\text{Area of rectangle} = 17 \times 18 = 306 \text{ square feet}.$

2. Area of the triangle:

   • The base of the triangle is 25 feet minus 17 feet (the length of the rectangle), which gives 8 feet as the base of the triangle.
   • The height of the triangle is given as 10 feet.
   • The area of a triangle is given by: $\text{Area of triangle} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 8 \times 10 = 40 \text{ square feet}.$

3. Total area:

   • The total area is the sum of the areas of the rectangle and the triangle: $\text{Total area} = 306 + 40 = 346 \text{ square feet}.$

The area of the shape is 346 square feet.
