Question

A man walks a square field of area 841/324 meter square.Find the distance covered by the man in 2 rounds

Answer 1

area of field = 841/324 m

side of field =√841/324 m

Answer 2

Area of the square field= 841/324 m. sqaure

So,

$side \: of \: field = \sqrt{area}$

$side = \sqrt{ \frac{841}{324} } \\ \\ = \frac{29}{18}m$

Distance covered by him in 1 round = field' s perimeter

=

$4 \times side \\ = 4 \times \frac{29}{18} \\ = \frac{58}{9} m$

Therfore,

Distance covered by him in 2 round=

$\frac{59}{9} \times 2 \\ = \frac{118}{9}m$

ANSWER= 118/9 metre

Hope it helps
