Answer
263 pavers are needed
Work Step by Step
$3 \frac{1}{3} = \frac{10}{3}$
$ 35 = \frac{105}{3}$
$\sqrt \frac{4}{9} = \frac{2}{3}$
$\frac{10}{3} \div \frac{2}{3} = \frac{10}{3} \times \frac{3}{2} =\frac{30}{6} = 5 $
$\frac{105}{3} \div \frac{2}{3} = \frac{105}{3} \times \frac{3}{2} =\frac{315}{6} = 52.5 $
$ 52.5 * 5 = 262.5$ (rounded to 263 pavers)
