"From the Ted Talk by Gordon Hamilton: Can you solve the Mondrian squares riddle?"

#### Unscramble the Blue Letters

Dutch artist Piet Mondrianâs abstract, rectangular paintings inspired mthiaamceatins to create a two-fold cagnhllee. First, we must completely cover a square canvas with non-overlapping rectangles. All must be unique, so if we use a 1x4, we canât use a 4x1 in another spot, but a 2x2 rcgetlnae would be fine.
Letâs try that. Say we have a canvas mrneiusag 4x4. We canât chop it directly in half, since that would give us identical rectangles of 2x4. But the next closest option - 3x4 and 1x4 - works.

#### Original Text

Dutch artist Piet Mondrianâs abstract, rectangular paintings inspired mathematicians to create a two-fold challenge. First, we must completely cover a square canvas with non-overlapping rectangles. All must be unique, so if we use a 1x4, we canât use a 4x1 in another spot, but a 2x2 rectangle would be fine.
Letâs try that. Say we have a canvas measuring 4x4. We canât chop it directly in half, since that would give us identical rectangles of 2x4. But the next closest option - 3x4 and 1x4 - works.
