Answer 2

i)616.1814398508

ii)865.9580292784

Step-by-step explanation:

FIRST ONE ANSWER:

$\sqrt{ {20}^{2} + {12}^{2} }$

$\sqrt{400 + 144}$

$\sqrt{544}$

$32 \times 20$

$640$

$640 - ( \sqrt{544} + \sqrt{544)}$

$= 616.1814398508$

SECOND ONE ANSWER:

$\sqrt{ {30}^{2} + {15}^{2} }$

$\sqrt{900 + 225}$

$\sqrt{1125}$

$\sqrt{ {15}^{2} + {15}^{2} }$

$\sqrt{225 + 225}$

$\sqrt{450}$

$900 - ( \sqrt{1125} + \sqrt{1125} + \sqrt{450} )$

$865.9580292784$
