Step-by-step explanation:

This is the basis of the Pythagorean Theorem that states that, in a right angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides.

So to be able to determine the area of the 3rd square, we have to add the areas of the other two squares together;

`225+64=289`
