Solution

Given that,
Diameter of the semicircle $= 7$ mtr
Then radius $= \frac{7}{2}$ mtr
Distance covered by semicircle $= π r$
$= \frac{22}{7} \times \frac{7}{2}$
Square side $= 11$ mtr
Sunita around $= 4 \times$ square side
$= 4 \times 11$
$= 44$ mtr
The side of square $= \frac{44}{4} = 11$ mtr
Hence, this is the answer.
