Question

5. In each side of a A is halved then its perimeter will be decreased by (a) 100% (b) 50% (c) 25%​

Answer 1

Answer:

It will decrease by 50%

Step-by-step explanation:

Let the sides of square be 4m

So the perimeter =

$4 \times 4 = 16m$

If we halved it so the sides will be 2m

Now the perimeter

$2 \times 4 = 8m$

So It will decrease by 50%
