A parallelogram’s perimeter is the total length covered by its boundary. The parallelogram contains four sides since it is a quadrilateral. The parallelogram’s perimeter equals the sum of these four sides. Geometry is a discipline of mathematics that studies various geometrical shapes.
A parallelogram is a four-sided two-dimensional geometric shape. A parallelogram has the following properties: A parallelogram’s opposite sides are parallel and equal to one another, In terms of size, opposite angles are equal, Parallelogram diagonals are bisected by each other.
Parallelogram
A parallelogram is a type of quadrilateral with two sets of parallel sides in Euclidean geometry. A parallelogram’s opposite or facing sides are of equal length, and the parallelogram’s opposite angles are of equal measure. The Euclidean parallel postulate follows directly from the congruence of opposite sides and opposite angles, and neither condition can be proven without employing the Euclidean parallel postulate or one of its equivalent formulations.
Characterisations
If and only if any one of the following claims is true, a quadrilateral is a parallelogram:
Parallel are two sets of opposed sides (by definition).
The lengths of two opposite pairs of sides are the same.
The measurement of two pairs of opposite angles is the same.
The diagonals are split in half.
One set of opposing sides is parallel and of equal length.
The quadrilateral is divided into two congruent triangles by each of the diagonals.
It exhibits second-order rotational symmetry.
Finding The Perimeter of a Parallelogram
The perimeter is computed by adding the lengths of all four sides. A parallelogram’s perimeter is the whole distance outside of the geometrical shape. A parallelogram’s opposite sides are equal, hence the perimeter is equal to the sum of two parallel sides.
Perimeter = 2(a+b)Units
The length of the regular pattern produced by a parallelogram’s boundary is its perimeter. It shares the same unit as its sides. If the opposite sides of a quadrilateral are parallel and of equal length, it is termed a parallelogram. A parallelogram has the following qualities. To put it another way, the perimeter of a parallelogram is equal to the total of its four sides.
The two sides are equal.
Angles on opposite sides are equal.
Diagonals cut each other in half.
Each pair of neighbouring angles is supplementary.
In the following situations, the perimeter of a parallelogram can be observed:
if two neighbouring sides may be identified.
If you identify one side and the diagonals.
When you identify the base, height, and any angle.
Finding Area of a Parallelogram
The area of a parallelogram in a two-dimensional plane is calculated as the region or surface that it covers. A parallelogram is a type of quadrilateral that is different from the others. A parallelogram is defined as a quadrilateral with two parallel opposed sides. Parallelograms include rectangles, squares, and rhombuses. Shapes, both 2D and 3D are important to geometry. Each shape has its own set of attributes and area formulas.
The total number of unit squares that can fit inside a parallelogram is called its area, and it is measured in square units (like cm2,m2,in2). A parallelogram is a four-sided, two-dimensional figure with the following properties: two equal and opposing sides, two intersecting but non-equal diagonals, and two equal and opposite angles.
Area of a Parallelogram formula
A parallelogram’s area is computed by adding its base by its altitude. A parallelogram’s base and altitude are normal to one another, The area of a parallelogram can thus be calculated using the formula:
Area = b×h square units
Here b is the base
And h is the height
Solved examples
Calculate the area and perimeter of a parallelogram whose base and height is 2 and 3 cm.
Solution: The area of a parallelogram is given as : b×h = 2×3 = 6cm2
The perimeter of a parallelogram is given as :2(a+b) = 2(2+3) = 2×5 = 10cm.
Conclusion
The computation of the space within a parallelogram’s four sides is known as its area. A parallelogram is a two-dimensional quadrilateral plane with equal and parallel opposite sides that comprises a rectangle, a rhombus, and a square. A parallelogram’s area is equal to the product of its length and height, and the sum of all its angles equals 360 degree. A parallelogram has both area and perimeter because it is a two-dimensional figure. Because a rectangle and a parallelogram have comparable features, the area of a rectangle is the same as the area of a parallelogram.
