The smaller square in the figure below has a perimeter of 8 cm, and the larger square has an area of 16 cm^2. What is the distance from point A to point B? Express your answer as a decimal to the nearest tenth.
by pythagorean theorem
AB = sqrt (2^2 + 6^2) This figure is obviously not to scale !
AB = sqrt [(4 + 2)2 + (4 - 2)2]
