# What is the formula for finding the area of a trapezoid?

Trapezoids are shapes having one set of parallel lines. They have many interesting properties and have many applications in various fields.

## Answer: The formula for the area of a trapezoid is 1/2 × (sum of the length of parallel sides) × height.

Let's understand the solution in detail.

**Explanation:**

Let's understand this with the help of an example.

Given below is a trapezoid with 'a' and 'b' as lengths of the parallel sides and 'h' as the height.

Let's say a = 5, b = 7 and h = 10.

Now, the area of trapezoid is given by 1/2 × (sum of the length of parallel sides) × height = 1/2 × (a + b) × h = 1/2 × (5 + 7) × 10 = 60 sq. units.
