Which of the following could be the perimeter of the three squares below?

I would say B

Step-by-step explanation:

I have done the calculations and my research matches B

XDDD

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

if x = 1, then the answer is 3.5
