Question

By doubling each dimension the area of a parallelogram increased from 36 square centimeters to 144 square centimeters. find the percent of increase in area

Answer 1

The percentage of increase in area will be 300%

Step-by-step 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
`= (108)/(36)*100 = 300`%
