A trapezium is a *convex quadrilateral*, which has only two parallel sides and the other two sides are non-parallel. The non-parallel sides of the trapezium are referred to as its legs while the parallel sides are called the bases. It is also called a trapezoid. A parallelogram is also often referred to as a trapezoid with two parallel sides.

In the figure below, AB and DC are parallel to each other while AD and BC are the non-parallel sides. ‘h’ is also the distance that indicates the height of the trapezium between the two parallel sides.

**Area of trapezium:**

Area = 1/2*(sum of parallel sides)*height of the trapezium

**Example:**

Input :base1 = 3, base2 = 4, height = 6Output:area = 21Input :base1 = 5, base2 = 7, height = 3Output:area = 18

**Approach:**

- Take three input as two bases of the trapezium and height.
- Apply the area of the trapezium formula to calculate the area.
- Print the area.

Below is the implementation of the above approach:

## Java

`// Java Program to Find the Area of Trapezium` ` ` `import` `java.io.*;` ` ` `class` `GFG {` ` ` `public` `static` `void` `main(String[] args)` ` ` `{` ` ` `double` `base_1 = ` `10.00` `;` ` ` ` ` `double` `base_2 = ` `20.00` `;` ` ` ` ` `double` `height = ` `50.00` `;` ` ` ` ` `// formula for calculating the area` ` ` `double` `area_of_trapezium` ` ` `= ((base_1 + base_2) * height) / ` `2` `;` ` ` ` ` `// printing the area` ` ` `System.out.println(` `"Area of trapezium:"` ` ` `+ area_of_trapezium);` ` ` `}` `}` |

**Output**

Area of trapezium:750.0
