5 is A, because it's the only number that is whole when square rooted. 6 is confusing because it only gives you one number per answer, unless you are to add the two distances together? Then it would be 7 because X's distance is +4 and Y's distance is +3 I do not have an answer for 7 8 is 3.7 (or C) 9 is an easy one. Find out what the L and W is, and since it's a square we only need to find one of them. We square root the area and we are given 14.96662955, if rounded we get 15. So the answer is A 10 I don't understand the "estimate" for a square root number, I was not taught that.
