please answer CORRECTLY and QUICKLY​

Answer 1

Answer:

Mark me as the brilliant please i need it ❤❤

Step-by-step explanation:

y=k x^n (Directly proportional)

(i) y m^2 = x^2 (area of a square is x multiplied by x so “x^2”)

So “n” in that question would be “2”.

(ii) y cm^2 = x^3 (volume of a cube is x multiplied by x multiplied by x so “x^3”)

So “n” in that question would be “3”.
