(1-0.2)(1-0.4)(1-0.62) = (0.8)(0.6)(0.38) = 0.1824
Answer: 0.1824
Answer in screen shot below
Area = width * height
since the window is 20 inches higher than the width:
width +20 = height
640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
