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:

Isosceles Trapezoid Area

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

Perimeter and Apotem Length

Area result


Where:

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

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".
