A trapezium of area 140 m has parallel sides 10cm apart and one of these sides is 16 cm long find the length of the other parallel sides?

The area of the trapezium cannot be 140 metres since the latter is a length, not an area. Suppose the area is 140 m2 = 1400000 cm2
Suppose the length of the second parallel side is x cm.
Area of trapezium = 1/2*(sum of lengths of parallel sides*distance between them)
ie 1400000 = 1/2*[(16+x)*10]
280000 = 16+x so x = 279984 cm = 2.79984 kilometres.

What is a quadrilateral with one pair of opposite sides parallel and the other pair of opposite sides congruent?
An isosceles trapezium
What is the formula for finding the area of tratrapezoid?
Area of a trapezoid = 1/2 of (length of one of the parallel sides + length of the other parallel side) times (distance between the two parallel sides)
What are trapezoids?
A trapezium (as it is known in English) is a quadrilateral which is a closed plane figure with four straight sides. It has one pair of parallel sides. The other pair of sides is not parallel (otherwise the figure would become a parallelogram).
What has 2 short sides and 2 long sides?
Definitely a quadrilateral. However, if the short sides are equal in length, and the long sides are equal in length then it could be a Kite, Rectangle or Parallelogram, depending upon whether the two short sides are next to, or opposite to, each other, and in the latter case if the angles are all 90° or not. Also, if two of the sides are parallel but the other two are not, then it could be a trapezium.
What does a parallel line look like?
In order to describe parallel, you need 2 lines to be parallel to each other. The lines will lie in the same plane, and the right-angle distance between the 2 lines will be constant for the entire length of the lines. Since lines are infinite length in length, they will never intersect.
Is a parallelogram a trapezium?
NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.
What is an iosocelus trapezium?
An isosceles trapezium has one pair of sides parallel to each other and the other pair that are of equal length (but facing in opposite directions). An isosceles trapezium can be imagined as an isosceles triangle whose top has been chopped off by a line parallel to its base.
Does a trapezium always have equal sides?
No. A normal trapezium has two parallel sides that are not equal in length, and two other sides joining the ends of the parallel sides which may be equal, but are usually not. If all four sides of a trapezium were equal in length, it would be called a rhombus as the sides would be parallel in pairs; and if the angles were 90° as well, it would be called a square.
Does a trapezium have a right angle?
Only if it was a rectangle, but then we wouldn't usually call it a trapezium. A trapezium should have a long and a short side parallel to each other with two other sides joining the parallel ones.
What polygon has one set of parallel lines?
A trapezoid or, in Britain, a trapezium. Other than in Britain, a trapezium is a quadrilateral with no parallel sides at all.
Do parallel lines have to be equal?
No not in length but they must be equal distance apart from each other.
What shape is a trapezium?
A trapezium is a shape with four sides. Of these, one pair of sides are parallel. The only restriction on the other pair is that they are not parallel (because you then have a parallelogram).
How does a trapezium have 1 pair of parallel sides?
A Trapezium has 1 pair of Parallel sides because it has 4 sides and 2 of them run along side each other but the other pair are both on different angles. Parallel lines are when 2 lines are at 1 distance apart without getting any closer or further away. Train Tracks are parallel lines. Sorry its hard to explain
The area of a Trapezium is 34 cmto the power 2 and length of one of its parallel sides is 10.4 cm and its height is 4 centimetre find the length of another parallel side?
The length of the other parallel side is 6.6 cm Check: 0.5*(10.4+6.6)*4 = 34 square cm
What quadrilateral has a pair of parallel sides?
A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
What features does a trapezium?
A trapezium has one set of parallel lines and the one of them has the lines of symmetry but the other one doesn't have any. Trapezium doesn't have perpendicular lines
What is the difference between an isosceles triangle and a trapezium?
One is a three-sided figure with two sides of equal length; the other is a four-sided figure with one pair of parallel sides.
