The base of the parallelogram is 5.45 cm.
To find the base of the parallelogram, we can use the following formula:
Area of parallelogram = base * height
We are given that the area of the parallelogram is 60 units^2 and the height is 11 cm. Therefore, the base is:
Base = Area of parallelogram / height
Base = 60 units^2 / 11 cm
Base = 5.45 cm
Therefore, the base of the parallelogram is 5.45 cm.
