Gmat practice test problem

it will be nice if you provide the picture to look at...

How do I copy the picture. Its on the the Gmat Practice Test 1 from MBA.com

use print screen button and paste in mspaint.

Here is the problem

my question is how is the square 2 its 2^2 right = 4

Think of R as two triangles put together rather than a square. Since the area of a triangle is (1/2)bh, the two triangles would be (1/2)(2)(1) + (1/2)(2)(1) = 2.

You can't just do base x height for a square using length 2 since the sides of the square are not 2 (or 1 depending on how you are looking at it on the graph), but sqrt(2), using the pythagorean theorem for a triangle (dividing the shape into 4 right triangles).

So base x height for the square would be (sqrt(2))(sqrt(2)) = 2

For R u have to Cut the square down the middle and take it as two triangles. theirs sides are not 2 since the square is not rightside up.

Ok I was thinking I could flip the square right side up

or

identify that for square R each side is sqrt 2. Then just multiply the sides sqrt2 X sqrt2 = 2
