1. According to Boyle's law, the volume V of a gas varies inversely to the pressure Pexerted by the gas. The volume of a given gas under a pressure of 32 kg per
cm² is 200cm3. What will be the volume of this gas when the pressure
exerted is 40 kg per cm??

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
