I need help on number 19 ! Please for brainless answer !!

Answer:
Yes
Step-by-step explanation:
We need to determine the sides of the squares
Area = 9
A = s^2
9 = s^2
Taking the square root of each side
sqrt(9)= sqrt(s^2)
3 =s
Perimeter of a square = 16
P =4s
16 =4s
Divide each side by 4
16/4 =4s/4
4 =s
Side = 5 in
Right triangles obey the Pythagorean theorem
a^2 + b^2 = c^2
Putting the smaller sides in for a and b
3^2 +4^3 = 5^2
9+16=25
25=25
Since this is true, we can arrange the squares to make a right triangle
Answer:
Yes, due to the Pythagorean theorem.
Leg A would be 3
Leg B would be 4
Hypotenuse C would be 5
Explanation:
When making the right triangle, only one side length value is needed.
If the area of square one is 9, 9 divided by 2 is 3.
If the perimeter of square two is 16, 16 divided by 4 is 4.
The single side length for square three is given, which is 5.
The Pythagorean theorem consists of a^2 + b^2 = c^2.
Plug in the values.
3^2 + 4^2 = 5^2
9 + 16 = 25
Hope this helps! :)
