I can see it. Is this question from GMAT?

Yeah, it’s from GMAT

If you look at both the statements you will find that they both give us the same information i.e length of one of the side of the triangle (in statement A its s^2 = 9 or s= 3). Now, we already given the area of the triangle so we plug this s value to find the missing side(bxh/2 = 4).Now when you get both the side use the Pythagoras theorem to find the length of the side of square A. Hence , Both statement are sufficient on their own. But if you’re struggling with these concept I cannot recommend enough the Princeton 164+ guaranteed course only for $1400(that’s a 20% discount than the normal rates)

Thank you! That is very helpful!

Hey Greg !

I guess the question has been answered already, but to see in a structured format we try to deduce the the sides of triangle from the area given of squares:

B^2 = 9

C^2 = 64/ 9

But we need those square for computation A so we can optimize time here and directly apply Pythagoras theorem instead calculating sides

Thus A^2 = 9 + 64/9 which comes equivalent to 4 , I guess

Dunno why but this question reminds me of 3 player chess
