Area of rectangular lawn= Area of square garden
l x b= a x a
54 x b = 27 x 27
54b = 729
b = 729 / 54 = 13.5
perimeter of rectangular lawn = 2(l+b)
= 2( 54 + 13.5)
= 2 x 67.5
=135 m
l x b= a x a
54 x b = 27 x 27
54b = 729
b = 729 / 54 = 13.5
perimeter of rectangular lawn = 2(l+b)
= 2( 54 + 13.5)
= 2 x 67.5
=135 m
