Question

two different rectangles having same perimeter then their areas are?

Answer 1

Step-by-step explanation:

Assume a square of side s and rectangle with one side as a and b.

Since, the perimeters are equal

4s = 2(a+b)

 b = 2s-a.

The sides of rectangle can be rewritten as a and 2s-a.

Areas are

s² and (2s-a)a

If they are equal :-

s² = 2sa - a²

s² -2sa + a² = 0

(s-a)² = 0

s=a

So, only when s = a, both perimeter and area are equal.

Answer 2

If two different rectangles have same perimeter then their areas will be same
