Answer:
6
Step-by-step explanation:
Given data:
x=area
f(x)=the length of one side of the square
Also the model of f(x)=
Now determining length of one side of the square f(x), when Area x of square is 26:
Putting the value x=26 in given equation of f(x)
f(x)=
=
= 5 +1
= 6
Hence length of one side of the square f(x) is 6, when Area x of square is 26 !
