Take off distance can be given as $S_{LO}=\frac{1.44W^{2}}{g \rho_{\infty}SC_{L,max}T}$Take-off distance is directly proportional to the square of weight of the aircraft therefore if the weight is increased by $$30 \%$$ take off distance will also increase to $$1.69$$ that is approximately $$70\%$$.
