The answer to this question is:
The side of a square is measured to be 12 ft with a possible error of ±0.1 ft. Use differentials to estimate the error in the calculated area. Include units in your answer?.
✔️X is the side
✔️A is the area of square.
✔️dA=d(X^2)=2X*dx----The error on A would be
✔️delta(A)=2*X*delta(X) = 2*10*0.1 (ft^2)=2 ft^2
✔️Then the error is +-2 ft^2
