2*12 = 24 cm.
no. Not necessarily. A rhombus is a parallelogram with equal adjacent sides. Gererally, though they will be unequal.
No. Adjacent sides, yes. (Twice the sum)
A parallelogram has adjacent equal sides. Diagonals of a parallelogram bisect each other,Opposite sides of a parallelogram are parallel and will never intersect. The area of a parallelogram is twice the area of a triangle created by one of its diagonals. Any line through the midpoint of a parallelogram bisects the area.
A rhombus
Perimeter of a parallelogram = 2 (A + B) 'A' and 'B' are the lengths of any two adjacent (touching) sides.
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
equilateral parallelogram
Parallelogram
A 'KITE' ; two adjacent sides may be of equal length. A parallelogram has two pairs of equal and parallel sides.
the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.
They can be but it's not necessary. When they are, it'sa special kind of parallelogram, called a "rhombus".
