The perimeter of parallelogram is 30 and 23 cm
What is Perimeter of Parallelogram?
The perimeter of a parallelogram is the length of its outline and hence it is equal to the sum of all its sides.
The perimeter of a parallelogram can be found in the following cases:
- When two adjacent sides are known.
- When one side and diagonals are known.
- When base, height, and any angle are known.
Here are the formulas to find the perimeter of a parallelogram in each of these cases:
- P = 2 (a + b), where a, b are the adjacent sides of a parallelogram
- P = 2a + √(2x2 + 2y2 - 4a2), where a is the a side of the parallelogram, and x, y are its diagonals.
Given:
sides are 8.5 cm and 6.5 cm
Perimeter of parallelogram
= 2 ( 8.5 + 6.5)
= 2 (15)
=30 cm
Perimeter of triangle
= s+ s+ s
=7.3 + 6.1 + 9.6
= 23 cm
