Answer:

A_{1} = 0.2 m^{2}

Explanation:

The pressure on the pistons is given as;

Pressure = \frac{Force}{Area}

So that,

Pressure on the small piston = \frac{F_{1} }{A_{1} } and Pressure on the large piston = \frac{F_{2} }{A_{2} }

Thus,

\frac{F_{1} }{A_{1} } = \frac{F_{2} }{A_{2} }

Given that: F_{1} = 100 N, F_{2} = 2000 N, A_{2} = 4 m^{2}.

\frac{100}{A_{1} } = \frac{2000}{4}

A_{1} = \frac{100*4}{2000}

    = \frac{400}{2000}

    = 0.2

A_{1} = 0.2 m^{2}

The area of the small piston is 0.2 m^{2}.
