The are of a square plot is 5625msq. Find the length of the wire that can go five times along the boundary of the plot​

Answer 1

Answer:

$area \: of \: a \: square \: plot = {5625m}^{2} \\ area \: of \: square \: = {a}^{2} \\ 5625 = {a}^{2} \\ a = \sqrt{5623} \\ a = 75m \\ perimeter = 4 \times side \\ = 4 \times 75 \\ = 300m \\ length \: of \: the \: fire \: for \: \\ 5 \: rounds \\ = 300 \times 5 \\ = 1500m$
