Trapezium :

Area(A) = 1/2 h(a + b)

where a and b are the length of the parallel sides

h= distance between two parallel lines .

Perimeter(P) = a + b + c + d

where a,b,c and d are the length of the sides.

Why does the formula of a trapezium work?

The formula for the area of a trapezium (or trapezoid) works by averaging the lengths of the two parallel sides (bases) and then multiplying by the height. This approach effectively transforms the trapezium into a rectangle with the same height and an area equivalent to that of the trapezium. By using the average of the bases, the formula accounts for the varying widths at either end, ensuring an accurate calculation of the total area. Thus, the formula ( \text{Area} = \frac{(b_1 + b_2)}{2} \times h ) captures the geometric properties of the shape.

How is the formula of a trapezoid related to the formula of a parallelogram?

Suppose you have a trapezium whose parallel sides (bases) are of lengths A and B units, and where the height is h units If you flip a trapezium over and append it to the original along one of the bases you will have a parallelogram whose base is A+B units in length and whose height is h units. So 2*Area of trapezium = Area of parallelogram = (A + B)*h
