Question

give 2 examples where the area does not increases when perimeter increases ???..

Answer 1

(1)
Let a rectangle whose length=3cm and breadth=2cm. So,
Area of rectangle =3*2=6cm
Perimeter of rectangle =2(3+2)=10cm
Now, let length=4 cm and breadth=1.5 cm. So, 
Area of rectangle =4*1.5=6 cm
Perimeter of rectangle =2(4+1.5)=11cm

​Thus, perimeter increases but area does not change.
