# Area of a Isosceles Trapezoid Formulas & Calculator

The area of a isosceles trapezoid can be calculated using the following formula: if you know the length of the bigger base, the length of the smaller base and the height.

## Formula Knowing the Bases and the Height

If you know the length of the bases and the height, you can calculate its area using the following formula:

$$"area" = h(a + b)/2$$

$$h = "hight value"$$
$$a = "Bigger base"$$
$$b = "Smaller base"$$

## Isosceles Trapezoid Definition

It is a geometric figure with 4 sides and 4 vertices, the isosceles trapezoid has 2 parallel sides and will always have diferent lengths betwen them; the other two sides are equal length.

The isosceles trapezoid in its bigger base has equal angles, and in its smaller base has also equal angles.

## Area Definition

It is the space of the internal surface in a figure, it is limited for the perimeter. Also, the area can be calculated in a plane of two dimensions.

## Formula Definition

It is a representation of a rule or a general principle using letters. (Algebra, A. Baldor)
When describing formulas in plural, it is also valid to say "formulae".
