Question

the length and breadth of a rectangular field are 405m and 80m respectively. find the length of each side of a square playground whose area is equal to the area of the rectangular field

Answer 1

area of a rectangular field=length × breadth

=32400


side of a square playground
$= \sqrt{32400}$

Answer 2

Given

Length = 405 m

Breadth = 80 m

Area of Rectangle = l x b

= 405 x 80

${32400m}^{2}$

Given :

Area of rectangle = Area of square

$area \: of \: square \: = {32400m}^{2}$

$area \: of \: square \: = {side}^{2}$

$32400 \: = {side}^{2}$

Side = √32400

Side = 180 m.

$\bold{Answer: \: The \: side \: of \: a\: square \: is \: 180 \: m}$
