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