## Area of 2D Shapes Formula Sheet

This sheet contains the formulas for calculating the area of various two-dimensional shapes.

**Triangles**

**Area = (1/2) * base * height**

Where:

**base**is the length of the base of the triangle.**height**is the perpendicular distance from the base to the opposite vertex.

**Squares**

**Area = side * side** or **Area = side²**

Where:

**side**is the length of one side of the square.

**Rectangles**

**Area = length * width**

Where:

**length**is the length of the rectangle.**width**is the width of the rectangle.

**Parallelograms**

**Area = base * height**

Where:

**base**is the length of any side of the parallelogram.**height**is the perpendicular distance from the base to the opposite side.

**Trapezoids**

**Area = (1/2) * (base1 + base2) * height**

Where:

**base1**and**base2**are the lengths of the two parallel sides of the trapezoid.**height**is the perpendicular distance between the two parallel sides.

**Circles**

**Area = π * radius²**

Where:

**π**(pi) is a mathematical constant approximately equal to 3.14159.**radius**is the distance from the center of the circle to any point on the circumference.

**Other Shapes**

Formulas for calculating the area of other shapes, such as **rhombuses, kites, and regular polygons**, can be found in various geometry textbooks or online resources.

Remember to use the appropriate units for the measurements when calculating the area. For example, if the measurements are in centimeters, the area will be in square centimeters (cm²).
