Question 397253: "The area of a square is 45 square centimeters. How long is the width?"
I tried taking 45 and finding the square root but, that only lead to 6.74687654387357, or something like that, and the answers are A-22 sqrt( 5 ) cm,
B-2 sqrt( 10 ) cm, C-20cm, D-10cm, E- 3 sqrt( 5 ) cm
After i saw this i tried finding perfect square roots that divided equally into 45 i think 9 is the only one so would the answer be E?

Question 397149: You have a rectangle with length of 9 ft. and width of 7 ft. You then have a similar rectangle with a perimeter of 260 ft. What is the length and width of the similar rectangle.
I believe if you multiply 7 and 9 by 8.125 you would get a length of 73.125 and a width of 56.875. Not sure if this is right, and even if it is I went through number by number until I got numbers that worked. Very time consuming and I'm looking for the method or formula that reaches the correct answer. Thanks.
