## anonymous one year ago Easy Question!! 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

x=16 $dx=\pm0.1$ $Area ~A=x^2$ $\frac{ dA }{ dx }=2x$ dA=2x~dx $dA=2*16*\left( \pm0.1 \right)=?$

2. anonymous

well 32 plus or minus 0.1 right?

3. anonymous

$\pm~3.2$

4. anonymous

oh okay so you multiply the .1 by the 32 , i see

5. anonymous
