Respuesta :

You can use the Pythagorean theorem for this question, because all three of the squares form a right triangle together.

A=24²+45²

The answer is the bottom choice.
According the Pythagorean theorem, the side length of A would be

√(25² + 45²)

This only the side length. In order to get the area, we have to square the side length.

[√(25² + 45²) ]²

= 25² + 45²

Thus, your answer is the last choice.
