Question

lenght = 64cm, weeadth - 36 min - what is perimeter ​

Answer 1

Answer:

Whenever the sum of two numbers is constant, the product is MAXIMUM when the two nunbers are AS CLOSE AS POSSIBLE!

Now, perimeter = 36

OR 2(L+B) = 36

OR L+B = 18.

Thus, produt will be MAXIMUM when L is as close to B as possible, or L = B.

OR L = B = 9 or Maximum area = 9×9 = 81 cm^2.

Thus, when will the area be minimum?

Keep the numbers AS FAR APART as possible.

So L = 17, B =1.

OR Minimum area = 17×1 = 17 cm^2.

Answer 2

Answer:

200 cm

Step-by-step explanation:

Length = 64

Breath = 36

Perimeter = 2x(l+b)

= 2x(64+36)

= 2x100

= 200 cm Ans.
