  1. A \(\frac {4}{3}\)
  2. B \(e^{2/3}\)
  3. C \(\frac {3}{2}\)
  4. D \(e^{3/2}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(e^{2/3}\)

Step-by-step Solution

Detailed explanation

The intersection point of \(y=x^{2}\) and \(y=\frac{1}{x}\) is \((1,1)\) Area bounded by the curves is the region \(\mathrm{ABCDA}\) is given as: \({\rm{ Area }} = \int_0^1 {{x^2}} dx + \int_1^t {\frac{1}{x}} dx\)…
