If one side of a parallelogram whose perimeter is42cm is 12cm , the measure of its adjacent side is.......................
it works just like a rectangle:
2(12+x) = 42
To find the measure of the adjacent side of the parallelogram, we need to understand the properties of a parallelogram.
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. This means that the adjacent sides of a parallelogram are equal in length.
In this case, if one side of the parallelogram has a length of 12 cm, we can deduce that the adjacent side also has a length of 12 cm.
Therefore, the measure of the adjacent side of the parallelogram is 12 cm.
