Area of a Trapezium

A trapezium is a quadrilateral that has only one pair of parallel sides.Consider the area of the following trapezium. To calculate the area of a trapezium, divide it into a rectangle and two triangles as shown below. Now, piece together the triangular ends so that the trapezium is divided into a triangle and rectangle.  The base of the triangle is the difference between the lengths of two parallel sides.  That is, a – b. Example 4 Find the area of the following trapezium. Solution: So, the area of the trapezium is 204 m2. Example 5 Find the area of the following trapezium. Solution: So, the area of the trapezium is 39 cm2. Remember: A trapezium is a quadrilateral that has only one pair of parallel sides. The area of the trapezium is given by the following formula where a and b are the lengths of the parallel sides and h is the perpendicular distance between the parallel sides.         calculation လုပ္မယ္                     ဗြီဒီယို
