1. **Problem Statement:** Find the perimeter and area of the given shape, which is a right triangle with a smaller square inside it at the bottom-left corner.
2. **Understanding the shape:** The large right triangle has legs of 4 in (vertical) and 3 in (horizontal), and the hypotenuse is 5 in. Inside it, there is a square of side 3 in at the bottom-left corner.
3. **Perimeter of the shape:** The perimeter of the shape is the sum of the outer sides of the large triangle since the square is inside and does not add to the outer perimeter.
4. **Calculate the perimeter:** The triangle sides are 3 in, 4 in, and 5 in.
$$\text{Perimeter} = 3 + 4 + 5 = 12$$
5. **Area of the triangle:** The area of a right triangle is given by
$$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$
Here, base = 3 in and height = 4 in.
6. **Calculate the area:**
$$\text{Area} = \frac{1}{2} \times 3 \times 4 = \frac{12}{2} = 6$$
7. **Area of the square:** The square has side length 3 in, so
$$\text{Area}_{square} = 3 \times 3 = 9$$
8. **Total area of the shape:** Since the square is inside the triangle, the total area of the shape is the area of the triangle minus the area of the square.
$$\text{Total Area} = 6 - 9 = -3$$
This negative value indicates the square cannot be inside the triangle as described with these dimensions; likely the square is part of the shape, so the problem likely asks for the triangle's perimeter and area only.
**Final answers:**
- Perimeter = 12 in
- Area = 6 square inches
Triangle Perimeter Area 4075F3
