Question

The length of a rectangle is increased by 25% while breadth is diminished by 30%.What is the impact on area? ​

Answer 1

Answer:

25-30-{(25×30)/100} = -5 -(30/4)

Then we get (-20 -30)/4= -50/4

So

-12.5 ,which is in decreasing order

So area is decreased by 12.5

Answer 2

30% increased the area
