The area of a trapezium is found because: 0.5*(sum of parallel sides)*height = area
The information given describes a square and not a trapezium. Area of the square = 3*3 = 9 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.
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.
Multiply the base*height*width.
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.
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

Multiply the height by the width
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.
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.
base times height divide 2
The answer will depend on the shape that you are considering.
Multiply the base*height*width.
