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

Facts about a trapezium?
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 of trapezium?
Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA
Formula for area of trapezium?
Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA
How can you find the area of a trapezoid using composite figures?
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
How do you work out the area of trapezium?
Area = 1/2*(sum of the parallel sides)*height
How do you find the area of a right angled trapezium?
a+b-h\2
Two parallel sides of the trapezium are 10m and 22m whose non parallel sides are 13m and 14m find the area of trapezium?
200.106m2
What is the formula for calculating the area of a trapezium?
area of trapezium=1/2{a+b}h
How do you find the cross sectional area of a trapezium?
1/2 ( a + b) x h
How do you find the base and height of a trapezium if you only have the area?
You cannot: there is not enough information to do so.
Facts about a trapezium?
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 of trapezium?
Area = 0.5*(sum of parallel sides)*heightNote: A trapezium in the UK is known as a trapezoid in the USA
What are the properties of height and trapezium?
The area of a trapezium is found because: 0.5*(sum of parallel sides)*height = area
How do you find the parallel sides of trapezium if we know the area and the length?
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.
What is the formula to find the area of a trapezium?
In UK terms:- Area = 0.5*(sum of parallel sides)*height and measured in square units
How do you find area of a trapezium?
A = half(a+b)h where h equals height and a and b are the parallel sides.
Area of the trapezium is?
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.
