Sanju, i am not sure what you are implying. The area of a triangle is ( 1/2 )*(b*h) Base X Height is 4/(sqrt 2) * 4/(sqrt 2), which I am certain is equal to 16/2 which equals 8. Now 1/2 * 8 (because we still need to multiply by 1/2 ) = 4. But 4 isn't an answer choice... Area of the Square is being ...

I'm not sure what I'm doing wrong here..4 coordinates are (0,2) (2,0) (0, -2) and (-2, 0).

That means that the diagonal of the square is 4 so each side is 4/(sqrt 2).

Area = base x height = 4/(sqrt 2) * 4/(sqrt 2) = 8 x 1/2 = 4.

But thats not one of the answer..

A little fuzzy on this probability concept

There was a post on this site that discussed this topic but I couldn't find it so I'm posting it again. A bag has 3 oranges and 2 apples, what is the probability of picking out an apple on the third try. I think the answer is 2/5, which is exactly the same probability as picking it out on the first ...

Awesome point, but aren't the directions for the SC section to choose the best possible answer out of the five choices? A lot of times all 5 answers are horribly structured and worded, but one is worded slightly less horrible. So in your example, question # 118 probably had 4 other choices which re...

I believe it is D. A and B use the word 'which' and that might incorrectly refer to night instead of the entire action of the temperature dropping. C uses the future tense "this will mean" when sentence is orginally in the past tense. E "emerging from the soil" is ambiguous becua...

The bald eagle, once endangered, has made such a dramatic comeback that the government is considering removing them from the list of endangered species. A. is considering removing them from the list of endangered species B. had considered removing them from the endangered species list C. considered ...

Hey Ian,

could you clarify if they were both the same number the answer would be 10?

I didn't quite understand that part. Thanks!

KMittal, you are absolutely correct. But at the end I think you meant to say that 43 is the only number that does NOT satisfy the criteria. The trick to doing these problems is to play with the information given, until you end up with the variables stated in the problem (in this case, j - k) just as...
