Find the length of a side of a square playground whose area is equal to the area of a rectangular field of dimensions 72 m and 338 m.
Length of rectangular field (l)−338 mand breadth (b)=72 m∴ Area=l×b=338×72 m2∴ Area of square=338×72 m2=24336 m2and length of the side of the square=√Area=√24336
=156 m
