Determine the calculated value using the given values in the given equations. Be sure to include the units in your answer. Using the error propagation method described above, calculate the percent error in the calculated value. For this exercise, your percent error is to be given to two significant figures. Hand in this answer sheet. Work the problems neatly on scratch paper and staple your work to this sheet.

A = xy, x = 3cm ± 0.1cm, y = 4.0cm ± 0.1cm
f = x + y
z = 3x + 2y
g = 2h/t² for h = 2.00m ± 3
