Question 1008906: Each side of a square have been increased by 20% soto make a big square.Find the percentage by which area increased
Answer by fractalier(6550)   (Show Source):
You can put this solution on YOUR website! You can do this a couple of ways, but let's call the side of the original square, x. The new square is 20% bigger, and then has a side of 1.2x.
Its area is (1.2x)^2 = 1.44x^2, which is 44% larger than the original x^2.
