What is the perimeter of a parallelogram
With base nine cm
side lengh twenty
seven cm and height twenty cm
please help me
height does not matter.
p = 2b+2s = 2*9 + 2*27 = 18+54 = 72
you only need the height if you want the area.
To find the perimeter of a parallelogram, you need to add the lengths of all four sides.
In this case, you're given the following measurements:
- Base: 9 cm
- Side length: 27 cm
- Height: 20 cm
A parallelogram has two pairs of equal-length sides, opposite and parallel to each other. The base and the top side are of equal length, and the two side lengths are also equal.
To calculate the perimeter, you need to first find the length of the other base. Since the opposite sides of a parallelogram are equal in length, the other base will also be 9 cm.
Now, you can calculate the perimeter by adding all four sides together:
9 cm (base) + 27 cm (side length) + 9 cm (other base) + 27 cm (side length) = 72 cm
Therefore, the perimeter of the parallelogram is 72 cm.
