Question

The area of square field is 34 m^2 . find its diagonal

Answer 1

it should be

1\2×diagonal^=34^2

diagonal=34

Answer 2

$\text{Area of a square of side }a = {a}^{2} \\ \\ given \: area = 34 \: {m}^{2} \\ \\ \Rightarrow {a}^{2} = 34$

$diagonal = \sqrt{ {a}^{2} + {a}^{2} } \\ \\ d = \sqrt{34 + 34} \\ \\ d = \sqrt{68} \: m \\ \\ d = 2 \sqrt{17} \: m$

Length of diagonal is 2√17 m
