Formulas for Calculating Area of Common 2D Shapes
To effectively work on an area of 2D shapes worksheet, students must familiarize themselves with the formulas for calculating the area of various shapes. Below are some commonly used formulas:
1. Rectangle
The area (A) of a rectangle can be calculated using the formula:
\[ A = \text{length} \times \text{width} \]
2. Square
For a square, where all sides are equal:
\[ A = \text{side}^2 \]
3. Triangle
The area of a triangle can be determined as:
\[ A = \frac{1}{2} \times \text{base} \times \text{height} \]
4. Circle
For circles, the area is calculated using:
\[ A = \pi \times \text{radius}^2 \]
(where π (pi) is approximately 3.14)
5. Parallelogram
The area of a parallelogram is given by:
\[ A = \text{base} \times \text{height} \]
6. Trapezoid
To find the area of a trapezoid, the formula is:
\[ A = \frac{1}{2} \times (\text{base}_1 + \text{base}_2) \times \text{height} \]
