please help me​

Answer 1

Answer:

Let there be a rectangle whose length is 10 cm and breadth is 8 cm.

Area of rectangle = L*B

= 10*8

= 80 sq cm

Perimeter of rectangle = 2(L+B)

= 2(10+8)

= 2*18 = 36 cm

Now,

Let there be another rectangle whose length is 20 cm and breadth is 4 cm.

Area = 20*4

= 80 sq cm

Perimeter = 2(20+4)

= 2*24

= 48 cm

So, in the above examples, area does not increase when the perimeter increases.
