Step-by-step explanation:
the square root of 27 is equal to:
We know that is an irrational number (but a real number), so is the same.
In case we need to prove that is irrational, please leave a comment.
Let x and y be the dimension of the rectangle. Suppose x is the width and y is the length. Since the perimeter is 36, we have
If we increase the length by 1, we change . Similarly, if the width is increased by 2, we change . So, the increased area is
If we substitute the value for y deduced in the first equation, we have
The solutions to this equation are
One of them is negative, so we have to choose the positive one:
Which implies
