Why do you not usually multiply the side lengths of a parallelogram to calculate its area?

To find area you need base and height of a parallelogram.
A = BH
Not all the side lengths given would be base or height. Side lengths are perfect to find perimeter but don't rely on the side lengths for area.

Do parallelograms have symmetry?
It depends on the parallelogram. There are usually no normal lines of symmetry, the rectangle and the square have 4.
Are diagonals on a parallelogram perpendicular bisectors?
No, they are just bisectors. The angle between them is not (usually) the 90o required to be perpendicular.
Do a parallelogram have 2 90 degree angles?
Not normally because a parallelogram usually has two equal opposite obtuse angles and two equal opposite acute angles that all add up to 360 degrees.
How do you calculate the length of the chord?
It is usually simpler to measure it. If you really want to CALCULATE it, the calculation (and whether you can calculate it at all) depends on what other information is available.
Do you multiply for area?
It depends what you are trying to get the area of. For example, to find the area of a square or rectangle you multiply the length times the width. But to find the area of a triangle, you multiply the height times 1/2 of the base. So yes, you usually multiply to find area of a figure, but there may be more steps to the process.
Does a parallelogram bisect?
Usually, a parallelogram with not bisect other shapes.
How do you calculate kgs into newtons?
You usually do this to calculate a weight. In this case, multiply the number of kilograms by the force of gravity - in case of Earth, this is about 9.8 meters/second2.
How do you calculate the fraction of a fraction?
Remember that in math, "of" usually means "times". To find a fraction of a fraction, multiply them.
How many right angles do a parallelogram have?
Usually zero. If your parallelogram happens to be a rectangle, 4.
How do you calculate lowest common multiple?
Usually you would multiply the two numbers together unless they could be reduced. If they could be reduced you would reduce them and then multiply them by each other.
Are all the angles of a parallelogram can be equal in size?
They can, but usually they are not. All the angles will be equal only if your parallelogram is a rectangle.
How many lines of symmetry has a parallelogram have?
Usually none.
How is the height of a parallelogram similar and different from the width of a rectangle?
The width of a rectangle is the same as one of its sides. That is not [usually] the case for a parallelogram.
Does a parallelogram diagonals cross at a right angle?
Yes * * * * * Usually not.
Are the adjacent sides on a parallelogram perpendicular?
Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.
Are all angles equal on a parallelogram?
THey can be (as in squares and rectangles) but usually aren't (as in rhombuses.)
How much does a tape measure in grams?
A tape measure is used to measure lengths. Lengths, on that scale, are usually measured in millimetres, centimetres, metre, inches, feet or yards. Lengths cannot be measured in grams.
