The side of a square is measured to be 16 ft with a possible error of ±0.1 ft. Use differentials to estimate the error in the calculated area. Include units in your answer.

What a horribly vague answer Steve. To someone who had a similar problem, you were of no help. can you at least say what the letters/variables represent?

steve is bad

To estimate the error in the calculated area of a square with a given side length and a possible error, we can use differentials.

Given:
Side length of the square, s = 16 ft
Possible error in the side length, Δs = ±0.1 ft

The formula for the area of a square is A = s^2.

To find the differential of the area, we differentiate both sides of the equation with respect to s:

dA = 2s ds

Now, we substitute the given values:
s = 16 ft
ds = ±0.1 ft

dA = 2(16 ft)(±0.1 ft)
dA = 3.2 ft^2

Therefore, the estimated error in the calculated area is 3.2 ft^2.

a = s^2

da = 2s ds
