Answer:
I am pretty sure it's #2 but wait for more ansawers because im not 100% sure.
Step-by-step explanation:
Answer: I think the correct answer is D.
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
So assuming scaled down it is
1:1.5 or
2:3
so
72 is the 3 units
divide 72 by 3
72/3=14
14 times 2=28
the surface area=28 in^2
