Area = \(16m^2\) hence side = \(4\)
Perimeter = \(16\)
Now when \(9m^2\) land is added, new area = \(25m^2\) ; side = \(5\)
New perimeter = \(20\)
Diff \(4\)
Answer A
Perimeter = \(16\)
Now when \(9m^2\) land is added, new area = \(25m^2\) ; side = \(5\)
New perimeter = \(20\)
Diff \(4\)
Answer A

area=16 m^2
area of square=side^2
so, side =4
perimeter=4*side
=4*4
=16
if new area =16+9 m^2
new area=25 m^2
side =5
new perimeter=4*side
=4*5
=20
difference= 4
that is option A
