Percentage Decrease in Area =(( Original Area - New Area )∕ Original Area )×100
Calculation:
Original Area =L×B
New Area =0.7L×0.9B
New Area =0.63LB
Percentage Decrease in Area =((L×B−0.63LB)∕L×B)×100
⇒ Percentage Decrease in Area =((LB−0.63LB)∕LB)×100
⇒ Percentage Decrease in Area =(0.37LB∕LB)×100
⇒ Percentage Decrease in Area =0.37×100
⇒ Percentage Decrease in Area =37%
