9. Which of the following could be the areas of the three squares below? A. 12 f12, 16 f12 and 20 f12 E B. 10 ft?, 18 ft2 and 30 ft2 C. 4 fi?, 5 f12 and 12 12 D. 8 f12, 16 f12 and 24 f12

Answer:
Explanation:
The squares given in the diagram form a right-angle triangle.
It has one of it's angles to be 90 degrees, which makes us to conclude that the triangle is right-angled.
To know what the possible areas of the three squares, we look for the PYTHAGOREAN TRIPLES in the option.
PYTHAGOREAN TRIPLES are three numbers that satisfy the Pythagorean theorem.
That is, the square of the longest side (hypotenuse) is equal to the sum of the squares of remaining two sides.
