  • Give two examples where the area increases as the perimeter increases.

ans:

For example, say you have a rectangle that is 20 x 10, perimeter = 60, area = 200. Increase the perimeter by adding 30 to both long and short sides and you have a rectangle that is 50 x 40, perimeter = 180, area 2,000. Sure enough, you increased the perimeter and the area increased.

  • Give two examples where the area does not increase when perimeter increases.

ans:

Let there be a rectangle whose length is 10 cm and breadth is 8 cm. Now, Let there be another rectangle whose length is 20 cm and breadth is 4 cm. So, in the above examples, area does not increase when the perimeter increases.

hope its help u

Solution:-

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.
