The length of the diagonal is found using the Pythagorean theorem
It is the square root of (162 +122 )=the square root of 400=20
Note, if you know about 3,4,5 triangles, then you could multiple each number by 4 and have a
12,16,20 triangle. The rectangle in question if made of two of those.

What is the length of the diagonal of a square with an area of 36?
Using Pythagoras: diagonal² = side² + side² = 2 × side² → side² = diagonal² ÷ 2 area = side² = diagonal² ÷ 2 → diagonal² = 2 × area → diagonal = √(2 × area) = √(2 × 36) = 6√2 ≈ 8.49
