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.
The area of a trapezium is found because: 0.5*(sum of parallel sides)*height = area
If the two parallel side of the trapezium are a and b and height of the trapezium (the distance between the parallel sides) is h then the area is given by:Area = 1/2 (a + b) x hHalf the sum of the lengths of the parallel sides times the distance between them.
A = half(a+b)h where h equals height and a and b are the parallel sides.
The information given describes a square and not a trapezium. Area of the square = 3*3 = 9 square cm
The length of the other parallel side is 6.6 cm Check: 0.5*(10.4+6.6)*4 = 34 square cm
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.
The area of a trapezium is found because: 0.5*(sum of parallel sides)*height = area
Which side lengths? To calculate the parallel sides, you need the height of the trapezium and one of the sides, and you substitute them into the formula: h(a + b)/2, where h = height, a and b are the parallel side lengths. If you want to find the sides that are not parallel, you need the parallel sides, as well as the height of the trapezium. Then, by using Pythagoras theorem, with the side length the hypotenuse, you can find their lengths.
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.
If the two parallel side of the trapezium are a and b and height of the trapezium (the distance between the parallel sides) is h then the area is given by:Area = 1/2 (a + b) x hHalf the sum of the lengths of the parallel sides times the distance between them.
It is: 0.5*(sum of its parallel sides)*height
Area of a trapezium = 0.5*(sum of parallel sides)*height
Area = 1/2*(sum of the parallel sides)*height
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.
A = half(a+b)h where h equals height and a and b are the parallel sides.
