Work done = f * s

work done = m * a * s

we need to prove

work done = m * a * s * s = m * a * (s)^2

therefore, s =s^2

therefore s=1

Just to complete your proof:-

$s=s^2$ gives $2$ solutions, namely $s=1$ and $s=0$ . But we cannot have $s=0$ , because then $m \times a \times s \times s$ will be $0$ . For an object, $mass$ can never be zero.
