Answer:
Step-by-step explanation:
The area of a rectangle is equal to 
, where 
is the length of the rectangle and 
is the width of the rectangle. In a rectangle, opposite sides are equal.
Therefore, we can write the following system of equations:
Expand the first equation:
Substitute the second equation into the first (
):
Solving for 
:
In geometry, there is a theorem that states: The sum of any two sides of a triangle is greater than that of the third
Let's try to plug in and find if any two sides added together will be greater than the third:
a) 2 cm
3+5=8 and 8>2 [acceptable]
2+3=5 but 5=5 [not acceptable]
2+8=10 and 10>5 [acceptable]
b) 3 cm
3+3=6, 6>5 [good]
3+5=8, 8>3 [good]
.....
etc
We found that the answer has to be 2cm, because if we were to add a side of 2cm with 3cm, it would equal to the third side and the theorem states that the sum has to be greater
