The area of a square plot is 2116 m². A man takes 5 rounds of the boundary of this plot, find the distance covered by him.

Area of square plot = l²

$l^2 = 2116m^2\\[1em] ⇒ l = \sqrt{2116m^2}\\[1em] ⇒ l = 46m$

Perimeter of square plot = 4 x l

$= 4 \times 46m\\[1em] = 184m$

The man take 5 rounds = 5 x 184m = 920m.

Hence, the total distance travelled by the man = 920m.
