Not him, but it's because the outer ends of the central "web" are hooked at the middle of the square's sides. No matter where you move that dot, the opposing sides will always equal the other opposing sides.

If we can pick only 28 or 32, then since the area has to be a square number, 32 works while 28 does not.

The exterior edges of each chunk have the same length (indicated by the || markings). Plus it's clearly a textbook exercise, those usually have nice, clean answers, so the area must be a perfect square

The exercise is not to calculate the blue area from first principles. The exercise is whether the blue area is 32 or 28.

We have an area of 32 to compare against. It's quite obvious that the blue area is smaller than 32.

Therefore, 28. QED.

32. It has to equal 100 because the area is too big for 81. 28 would mean the area is 95 which isn't a perfect square. The answer choice constriction is what makes this question possible

the sqrt(Area) doesn't need to be a whole number, retard. the Area could be 4.31^2. you don't even understand what the other brainlet's argument is. and the dumbest part is that 96 = (4*sqrt(6))^2 which is still not a perfect whole number square, and in fact 32 would complete the are to 10^2 which by his logic should be the correct answer, but obviously it's not. >>11641239

Wrong problem. You forgot the entire premise of this entire discussion:

Irrational numbers were never an option. Never.

>you can't have a non-integer number that when squared gives you an integer
Think dumb dumb, you can have a square that has an area of either 100 with sides of 10 or 96 with sizes of sqrt(96), nowhere does it say the sides of the square is an integer. You've never seen a square with a side of 2.5x2.5 cm?
