A rectangular building lot is

`(W=571+-21)m`

by

`(L=811+-31)m`

. In providing your answers for this question, use the strict use of significant figures for the uncertainty. That is only one significant digit for most cases. a) Provide the uncertainty on the width of the lot in the correct number of significant Figures

`\Delta W=`

b) Provide the width of the lot in the correct number of significant Figures based on the value of the uncertainty.

`W=`

c) Provide the perimeter of the lot with the correct number of significant figures based on the values of the width and length (remember not to round your result until you finish the calculations)

`P=`

d) Provide the area of the lot with the correct number of significant figures based on the values of the width and length

`A=`

e) Provide the uncertainty on the perimeter of the lot.
