If all four sides are 9, then the altitude isn't needed in order to answer the question.
I'm not even sure that an altitude of 12 is possible with sides of 9, but I don't care.
You only asked for the perimeter, and if the sides are 9, then the perimeter is 36 .
With perimeter 10 and all sides equal fora rhombus, each side (base) is 10/4 = 2.5 inch Area = base times altitude = 2.5 x 12 = 30
The perimeter of a parallelogram is not enough to determine its length. Let 6 ≤ A < 12 units be the length of the parallelogram and let B = (12 - A) units be its breadth. Then the perimeter of the parallelogram will be 24 units. But A is any one of infinitely many values between 6 and 12. So the dimensions are indeterminate.
The perimeter would be (12 + 8) x 2 which is 40.
The perimeter is 40 meters.
Perimeter = 4*12 = 48 inches
Since a parallelogram has opposite sides parallel and EQUAL, perimeter is 12+12+5+5 = 34 feet
12
If the parallelogram is sideways like the small sides are crooked and the bottom lines are straight then you have to add all the sides to get your answer.Measure any two adjacent sides. Sum them, then multiply by two.It's the sum of the lengths of all sides that form a parallelogram.Perimeter is the distance around an object. If we have a parallelogram with a length 12 and width 5, then 5+5+12+12 which is equal to 34. Same with trapezoid, rectangle, triangle, star, etc.P = 2l + 2w
2*12 = 24 cm.
With perimeter 10 and all sides equal fora rhombus, each side (base) is 10/4 = 2.5 inch Area = base times altitude = 2.5 x 12 = 30

To find the perimeter of any polygon just add the length of everyside. In this case you have 4 sides with a length of 12 in. so 12 + 12 + 12 + 12 = perimeter. or to simplify 4 * 12 = perimeter.
No, it cannot be. A dodecagon must have 12 sides (only) and 12 angles (only). A parallelogram has to have 4 sides (only) and 4 angles (only). Hence a dodecagon cannot be a parallelogram.
The perimeter is 40 meters.
There are infinitely many possible lengths for its sides. Select any number A, between 0 and 3 and let B = 6 - A Then a parallelogram with opposite sides of A cm and B cm will have a perimeter of 12 cm. Each of these parallelograms can come in infinite many shapes since the angle between the sides can vary infinitely.
The perimeter of a dodecagon is the sum of the lengths of its 12 sides. These sides may be of different lengths.
