Answer:
15cm
Step-by-step explanation:
The formula to calculate the area of a parallelogram is base x height.
Since we know the height and area, we can write the equation:
135 = base x 9
Now we can just divide 9 from both sides to solve for base:
135/9=basex9/9
So we get:
Base = 135/9=15
The length of the base is 15cm.
