base times height divide 2
bigger base + smaller base x height/2
The formulae are quite similar; you multiply base x height, where the height is perpendicular to the base. In the case of a trapezium, you need to calculate the average of the two bases first.
You cannot: there is not enough information to do so.
Area = a [(b1 + b2)/2]a = altitude (height) of the trapezoidb1 = length of one baseb2 = length of the other base
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
volume of trapezium = 1/2* (a1+a2)*h* length where a1,a2 are the base areas respectively and h is the height its a good formula but here is a easier one 1/2*(Area of top + Area of bottom)*Height*lenght
