Answer 2

Answer:

370

Step-by-step explanation:

~~~~~~~~~~~~~~~~~~~~~~~~~~~

LET THE LENGTH OF THE GARDEN BE 3x

LET THE BREADTH OF THE GARDEN BE x

Area of rectangle = l x b

16428 = 3x * x

16428 = 3x^2

16428 = 3x^2

16428/3 = x^2

5476 = x^2

root 5476 = x

LENGTH =3x = 3*74 = 222

BREADTH = x = 74

PERIMETER OF A RECTANGULAR PLOT=2 (L+B)

=2 (74+222)

=2*296

= 370 m
