Step-by-step explanation:
[tex]a) \\ {3.15}^{2} = 9.9225 \\ 5.25 ^{2} = 27.5625 \\ 9.9225 + 27.5625 = 37.485 \\ \sqrt{37.485} = 6.1224[/tex]
this means this isn't right.
b)
[tex]60 {}^{2} = 3600 \\ 48 {}^{2} = 2304 \\ 3600 + 2304 = 5904 \\ \sqrt{5904} = 76.837[/tex]
which means it isn't correct
There both wrong
Brainliest please :)
