Question

The breadth of a rectangle is increased by 2 units. Its perimeter is now increased??

Answer 1

Yes the perimeter is increased.

Explanation:PERIMETER OF RECTANGLE=2×(LENGTH +BREADTH)

Answer 2

The perimeter of rectangle increases.

Step-by-step explanation:

We are given the following in the question:

The breadth of a rectangle is increased by 2 units.

Let l be the original length and b be the original breadth.

New breadth = b + 2

Perimeter of rectangle =

$P = 2\times (l + b)\\P = 2l + 2b$

Perimeter of new rectangle =

$P' = 2\times (l + b')\\P' = 2\times (l + b + 2)\\P' = 2l + 2b + 4\\P' = P +4$

Hence, the perimeter of rectangle increases.
