I hope this will help you

Answer 2

Answer:

0.25% decrease

Step-by-step explanation:

⇒ Let the original length and breadth be x and y

∴ Original area = xy

⇒ New area (x− 5x/100)(y-5x/100)=

95/100 × (105/100)xy=0.9975xy

⇒ Difference in area = xy−0.9975xy

⇒ Difference in area = xy(1−0.9975)

⇒ Difference in area = xy(0.0025)

∴ Area decreased by 0.25%
