Hello,
We know that th formula for the area of a rectangle is:
Now, the problem in this excercise is that there is no restriction on the values that b and h can take, so, they can take any value provided that it meets:
for example:
But if they can only take intenger values, what we have to do is to descompose 12, and then we can analyze the possible solutions.
12 | 2
6 | 2
3 | 3
1
12= 2 *2*3
first option:
12=4*3
Answer: lenght= 4cm and width= 3cm or vice versa
second option:
12=2*6
Answer: lenght= 6cm and width= 2cm <span>or vice versa</span>

Add 1 to both sides:
In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that
Under this assumption, we square both sides and we have
The solutions to this equation are
But since we can only accept solutions greater than -1, we discard and accept
.
In fact, we have
and
which is the only solution.
