Solution: area of first portion=area of second portion

\int_{0}^{a} (2 x) (d x) = \int_{a}^{4} (2 x d x

2 (\frac{x ^{\frac{3}{2}}}{\frac{3}{2}})_{0}^{a} = 2 (\frac{x ^{\frac{3}{2}}}{\frac{3}{2}})_{a}^{4}

a^{\frac{3}{2}} = 4^{\frac{3}{2}} - a^{\frac{3}{2}}

2 a^{\frac{3}{2}} = 2^{2 \cdot (\frac{2}{3})}

a = 4^{\frac{2}{3}}
