Answer: 20 feet by 20 feet.
Step-by-step explanation:
1. You know that
is the original measure of one side. Since it is a square, all its sides are equal.
2. Therefore, to solve the problem you only need to solve for
, as you can see below:
- You have that:

- Then, you obtain the following quadratic equation:

- Apply the Quadratic formula to solve it:

- Then, you obtain:

3. The dimensions cannot be negative, therefore, the answer is: 20 feet by 20 feet.
Step-by-step explanation:
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
