उत्तर

This statement is True.

Explanation:

Because the perimeter is the sum of all sides of closed shapes or polygons while the area is just bounded space insides.

Let’s take example of parallelogram

Their corresponding height and sides may different.

Thus, perimeter cannot be equal, even though area is equal.

Example:

Parallelogram 1: Side 1 = 6, 

Side 2 = 3, 

Height with side 1 base = 2.5

So, Area = 6 × 2.5 = 15

And perimeter = 2 × 6 + 2 × 3 = 12 + 6 = 18

Let, parallelogram 2: Side 1 = 5,

Side 2 = 3.5, 

Height with side 1 base = 3

So, Area = 5 × 3 = 15

And perimeter = 2 × 5 + 2 × 3.5 = 10 + 7 = 17
