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

Where a and b are the lengths of the two parallel lines which form the base and top of the shape.

(Half the sum of the parallel sides) X (the distance between them)

That's how my maths teacher taught us. Here is the song, it goes to the tune of pop-goes-the-weasel.

Half the sum of the parallel sides

Times the distance between them

A trapezium is a quadrilateral (has four sides). Two sides are parellel, but the other two are not. To find the area of it, the formula is: 1/2 h(a+b)

Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA

Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA

Suppose the base and parallel sides of the trapezium are labelled a and b. Suppose, also, that the distance between a and b is h. Draw a diagonal. This will split the trapezium into one triangle whose base is the trapezium's base (a) and another upside-down triangle whose base is the trapezium's top (b). The heights of both these triangles will be the same as the distance between the parallel sides of the trapezium (h). The area of the first triangle is 0.5*a*h The area of the second triangle is 0.5*b*h So the area of the trapezium = 0.5*a*h + 0.5*b*h = 0.5*(a+b)*h

Area = 1/2*(sum of the parallel sides)*height

You cannot: there is not enough information to do so.

A trapezium is a quadrilateral (has four sides). Two sides are parellel, but the other two are not. To find the area of it, the formula is: 1/2 h(a+b)

A trapezium has a pair of parallel sides of different lengths so in order to find its 2nd parallel side the information given must include its height.

Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA

The area of a trapezium is found because: 0.5*(sum of parallel sides)*height = area

In UK terms:- Area = 0.5*(sum of parallel sides)*height and measured in square units

A = half(a+b)h where h equals height and a and b are the parallel sides.

Let the two parallel sides be a and b, and the distance between them, the height of the trapezium, be h. Then: area of trapezium = 1/2 (a+b) h That is half the sum of the two parallel sides times the height of the trapezium.
