Answer 2

Answer:

area of field= 28224 m sq.

as we know,

$area = (side) ^{2}$

$(side) ^{2} = 28224$

$side = \sqrt{28224}$

$side = 168m$

as we know,

$perimeter \: of \: square = 4a$

$perimeter = 4 \times 168$

$perimeter = 672$

$cost \: of \: fencing = perimeter \times cost$

$= 672 \times 15$

$= 10080$
