Answer:
The correct answer is 2.
Step-by-step explanation:
Given y is directly proportional to x raised to the power n.
⇒ y [tex]\alpha[/tex] [tex]x^{n}[/tex]
⇒ y = p × [tex]x^{n}[/tex] with p being the constant of proportion.
Let y be the area of a square of side x meters.
Therefore y = [tex]x^{2}[/tex] square meters.
Now according to the given problem, comparing both the above mentioned equation we get the value of n equal to 2.
