Give the areas volume and perimeter of the square,rectangle,circle and triangle

Here’s a comprehensive explanation of the area, volume, and perimeter formulas for **squares, rectangles, circles, and triangles**:

---

### **1. Square**
- **Area**: \( A = s^2 \), where \( s \) is the side length of the square.
- **Perimeter**: \( P = 4s \).
- **Volume** (if considering a cube): \( V = s^3 \).

---

### **2. Rectangle**
- **Area**: \( A = l \cdot w \), where \( l \) is the length, and \( w \) is the width.
- **Perimeter**: \( P = 2(l + w) \).
- **Volume** (if considering a rectangular prism): \( V = l \cdot w \cdot h \), where \( h \) is the height.

---

### **3. Circle**
- **Area**: \( A = \pi r^2 \), where \( r \) is the radius.
- **Perimeter (Circumference)**: \( C = 2\pi r \).
- **Volume** (if considering a sphere): \( V = \frac{4}{3}\pi r^3 \).

---

### **4. Triangle**
- **Area**: \( A = \frac{1}{2} \cdot b \cdot h \), where \( b \) is the base, and \( h \) is the height.
- **Perimeter**: \( P = a + b + c \), where \( a, b, c \) are the side lengths.
- **Volume** (if considering a triangular prism): \( V = A \cdot h_{prism} \), where \( h_{prism} \) is the height of the prism.

---

### Additional Notes:
1. For the **volume** calculations of 3D shapes (cube, rectangular prism, sphere, triangular prism), you’ll need an additional third dimension, typically called height or depth.
2. To solve these formulas numerically, substitute the respective lengths, radii, or dimensions.

#### **Tip:** 
Always ensure the units (e.g., cm, m) are consistent when calculating area, perimeter, or volume to avoid errors.
