#Area of isosceles trapezoid calculator how to#

The total area of the triangles will be the area of the trapezoid.Įxample 1: If the bases of a trapezoid are 30 inches and 20 inches. We will calculate the area of the triangles separately. On implementing it in the formula:Īrea of trapezoid (A) = ½ * h * (b1 + b2)Īnother way to calculate the area of a trapezoid by dividing the trapezoid into two triangles. The area of a trapezoid is the average width times the altitude. To find the area of the trapezoid follows the steps below: Scalene trapezoid: A trapezoid shape that has neither equal sides nor equal angles.In the following image, the sides AD and BC are of the same length. Isosceles trapezoid: A trapezoid shape that has an equal length of non-parallel sides.Right trapezoid: It contains a pair of right angles.Each base must be perpendicular to the height.A trapezoid can be a rectangle if both pairs of its opposite sides are parallel its opposite sides are of equal length and are at right angles to each other.A trapezoid is a square if both pairs of its opposite sides are parallel all its sides are of equal length and at right angles to each other.The perimeter of the trapezoid is 'P', and 'H' is the height of the prism. In this formula, 'b1' and 'b2' stand for the length of the bases of the trapezoid. A trapezoid is a parallelogram if both pairs of its opposite sides are parallel. The surface area of a trapezoidal prism can be given with this formula: (b1+b2)h + PH.The altitude is perpendicular to the distance between two bases.

In the following figure, base 1 and base 2 are perpendicular to the dotted line, which represents the altitude (height). The parallel sides can be horizontal, vertical, or slanting (diagonal). The parallel sides are known as base, and the non-parallel sides are known as leg. The trapezoid is a gematrical shape that has four-sides in which a pair of opposite sides must be parallel is called trapezoid.

In this section, we will learn how to find the area of a trapezoid.

It means that a closed-shape that has four sides with one pair of parallel sides. The trapezoid is a convex quadrilateral shape.
