Answer:
A
Step-by-step explanation:
The length of sides would be A/4, B/4 and C/4 where A, B, and C are the perimeters of the three squares.
As the triangle is a right triangle,
c² = a² + b²
only answer A with sides 3, 4, and 5 will fulfil Pythagorean theorem.
B sides are 5, 4, and 6
C sides are 10, 20, and 30
D sides are 4, 6, and 7
