Two waves are traveling through the same container of air. wave a has a wavelength of 2.0m. wave b has a wavelength of 0.5m. the speed of wave b must be the speed of wave a. a) the same as b) greater than c) 1/4 as fast as d) must less than

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

one that is bigger than 3 1/2
