Can you please help me solve this problem> If each of the dimensions of a rectangle is increased by 100% , by what percent is the area increased.
There is an important difference in the ways the new area could possibly be stated.
The new area is 4 times what it was before.
2L x 2W = 4LW
So the new area is four times the old area of LW
or 400% of the old area.
But the increase in area is 300%
Increase is looking for the difference between the old and new.
4LW - LW = 3LW increase
So the increase in area is 3 times what the old area was
or the increase in area is 300%.
Since according to your question you are asked for the percent increase,
the answer would be "the area is increased by 300 precent".
