bigger base + smaller base x height/2
area of trapezium=1/2{a+b}h
The area of a trapezium is given by 0.5*(a+b)*h where a and b are the lengths of the parallel sides and h is the vertical distance between them. The fact that the trapezium is isosceles does not matter. A trapezium is a 2 dimensional object and so it has no volume.
1/2 h(a+b)
In UK terms:- Area = 0.5*(sum of parallel sides)*height and measured in square units
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.
yes u can calculate the perimeter of a trapezium
In that case, it would be good to know WHAT is given. If NOTHING is given, you really can't calculate.
How do you calculate the centroid of a trapezium when using geometic picture
Let's call the parallel sides A and B, and the distance between them as H. The area of the trapezium, or K, is (A+B)H/2. K = (A+B)H/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.
the sides ofn trapezium are 11.3cm 14.5cm, 11.1cm, and 6.5cm. The perpendicular height is 10.4cm calculate the are giving your answer to an appropriate degree accuracy try this instead 1/2*(Area of top + Area of bottom)*Height
area of trapezium=1/2{a+b}h
Not too sure of the question but the area formula for a trapezium is: 0.5*(sum of parallel sides)*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
trapezium surface area = 1/2 * (parallel-side-1 + parallel-side-2) * height = 13/2 * height height (assuming isosceles trapezium) = sqrt (10 squared - (3/2) squared) = sqrt (100 - 9/4) ~ 10 area ~ 65 cm squared.
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.
