Jackie plans to place a rectangular piece of art inside a rectangular frame. She considers a piece of art that is 0.5 meters long, 1.2 meters wide, and has a diagonal length of 1.3 meters.

Which is true regarding the art piece?
The art is rectangular because (0.5) squared + (1.2) squared = (1.3) squared.
The art is rectangular because (1.2) squared minus (0.5) squared less-than (1.3) squared.
The art is not rectangular because (0.5) squared + (1.2) squared not-equals (1.3) squared.
The art is not rectangular because (0.5) squared + (1.2) squared greater-than (1.3) squared.
