The percentage of increase in area will be 300%
Explanation
By doubling each dimension, the area of a parallelogram increased from 36 square centimeters to 144 square centimeters.
So, the increased area = Final area - Initial area = (144 - 36)cm² = 108 cm²
Now, for finding the percentage of increase, first we need to divide "the increased area" by the "initial area" and then multiply by 100%
Thus, the percentage of increase in area [tex]= \frac{108}{36}*100 = 300[/tex]%
