You can measure it. Or you can calculate it. The details of the calculation depend on what information is given.
Since in a parallelogram, two opposite sides are congruent, then the perimeter of the given parallelogram is 30 in [2(7 + 8)in].
A square.
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)
Perimeter = 4 times the square root of the 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.
Multiply the height by the width
If no side lengths are given, then no perimeter is defined.Even if you know all four angles in the parallelogram, it could still be drawn on thehead of a pin or on the floor of the Grand Canyon, with the same angles.But let's look on the bright side: If someone said to you "I have this parallelogram.What is its perimeter ?", then you could pick any number you want out of the blue,and he could not say that you're wrong. A parallelogram could be drawn that hasthe perimeter you gave, and matches all the numbers that he gave.
Please clarify what data is given, and what you want to solve for. To calculate the perimeter, add the length of all four sides. To calculate the area, the formula is basically same as for a rectangle: length x height; however, the height must be measured perpendicular to the side which you use as "length".
it depends on the shape. the unit should be given
use your ruler to measure the sides
