Question

What is the change in the area of a rectangle if its length is doubled and breath is halved?​

Answer 1

Answer:

It will be same

Step-by-step explanation:

We will solve it by an example

Let the length be 4m and bredth be 2m so the area will be

$4 \times 2 = 8 {m}^{2}$

Now Double the length = 8m

and half the breadth =1m

Area=

$8 \times 1 = {8m}^{2}$

Thus It will remain same

Answer 2

Answer:

Since, we know area of a rectangle=length×breadth

1)If its length is doubled and breadth is halved, the area remains same.

2) If its length is doubled and breadth remains the same, then the area becomes twice that of the original one.

3) If its length and breadth both are doubled, then its area becomes 4 times of the original one.
