Step-by-step explanation:
The length, width and diagonal of the rectangle form a right-angled triangle.
Here, diagonal forms the hypotenuse, so Pythagoras Theorem is valid to compute the length of the diagonal.
Note: We do not consider the negative square root value since the diagonal is a length so cannot be negative.
