It is an isosceles trapezium
The description given fits that of an isosceles trapezoid whereas non parallel sides are equal in length and base angles are equal in sizes.
A trapezoid would fit the given description.
To prove that the line which divides the nonparallel sides of a trapezium proportionally is parallel to the third side, we can use the property of similar triangles. Let the trapezium ABCD have sides AB and CD as the nonparallel sides, and side BC as the third side. Let the line dividing AB and CD be denoted as EF, with E on AB and F on CD. By the property of similar triangles, we can show that triangles AEF and BCF are similar, and hence their corresponding angles are congruent. This proves that EF is parallel to BC.
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.
I am assuming the question refers to a quadrilateral (quaratual) with two obtuse angles and two acute angles, and its opposite (oppoisite) angles (angliews) are not equal (equlal)! It could be a trapezium or a quadrilateral with so specific name. Quadrilaterals with equal angles or equal sides, or parallel sides are given special names but there is no specific name for quadrilaterals which do not have any of these characteristics.
It is necessary to know which of the five given measures refer to the trapezium [cross section] and which one is the length of the prism. Furthermore, it is necessary to know which two of the four sides of the trapezium are the parallel ones.It is necessary to know which of the five given measures refer to the trapezium [cross section] and which one is the length of the prism.

The special name given to a parallelogram with all side equal is a RHOMBUS.
In that case, it would be good to know WHAT is given. If NOTHING is given, you really can't calculate.
trapezoid or a trapezium (depending on where you are)
Histogram
The information given describes a square and not a trapezium. Area of the square = 3*3 = 9 square cm
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.
