Answer: 1.115 · 10⁻⁴ m²

Explanation:

The capacitance (C) of a parallel plate capacitor is given by the formula:

C = ε₀A/d, where:

  • ε₀ is the constant for permittivity of free space (8.85 · 10⁻¹² F/m)
  • A is the area of the plates
  • d is the distance between the plates

We are given:

  • C = 1.11 · 10⁻⁹ F
  • d = 8.89 · 10⁻7 m

Let's plug these values into the formula:

1.11 · 10⁻⁹ = (8.85 · 10⁻¹²)(A)/(8.89 · 10⁻7)

Solve for A:

A = 1.115 · 10⁻⁴ m²

The area of the plates must be 1.115 · 10⁻⁴ m².
