The sound level, , in decibels (dB), of a sound with an intensity of I is calculated in relation to the threshold of human hearing, , by this equation.

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
