![]() So from given area, base lengths the height of an isosceles trapezium is 4.8cm Perimeter of Isosceles Trapezoid Length of parallel sides (a) = 6cm, b = 4cm Question 2: Find the height of isosceles trapezium if the length of parallel sides are 6cm, 4cm and area is 24cm 2. Length of parallel sides (a) = 7cm, b = 5cmĪrea of given isosceles trapezoid is 24cm 2. Question 1: What is the area of isosceles trapezium if the length of parallel sides are 7cm, 5cm and height is 4cm. To get more understanding let’s solve a few examples Sample Problems on Area of Isosceles Trapezium The area of the Isosceles Trapezoid can be calculated by adding the lengths of two parallel sides (bases) and dividing this by 2 and multiplying the result with the height of the trapezium to get the area. A trapezium is called an Isosceles trapezoid when two opposite sides (Bases) are parallel and the other two sides (legs) are of the same length.Īrea and Perimeters are the formulas of Isosceles Trapezoid. Isosceles Trapezoid is a trapezium with congruent base angles and congruent non parallel sides. There are three types of Trapezoids and Isosceles Trapezoid is one of its type. Trapezoid is a quadrilateral in which a pair of opposite sides are parallel. ![]() The Perimeter of isosceles trapezoid formula is Isosceles TrapezoidĪn isosceles trapezoid (called an isosceles trapezium by the British Bronshtein and Semendyayev 1997, p. 174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal.įrom the Pythagorean theorem, Isosceles Trapezoid Formulas There are two isosceles trapezoid formulas Isosceles trapezoid is a type of trapezoid where the non-parallel sides are equal in length. The unique property about the trapezoid is that it has only one pair of parallel sides.
