1.

1)

$\sqrt{49 } = 7$

2)

$6 \sqrt{2} = \sqrt{ {6}^{2} \times 2} = \sqrt{36 \times 2} = \sqrt{102}$

$5 \sqrt{3} = \sqrt{5 ^{2} \times 3 } = \sqrt{25 \times 3} = \sqrt{65}$

$6 \sqrt{2} > \sqrt{3}$

3)

$\sqrt{ {5}^{2} - {3}^{2} } = \sqrt{25 - 9} = \sqrt{16} = 4$

5)

$p = l \times 4 = 7 \times 4 = 28$
