$1.$ Using the given elevations for points A $$ F$,$ draw contours inside the arbitrary closed shape on a $1-$ft

contour interval. Round measured lengths to the nearest foot. Use a scale of $1$ inch $=10$ ft$.$

Document your calculations.

Point Elevation $($ft$)$

A $27\mathrm{.}27$

B $26\mathrm{.}17$

C $23\mathrm{.}67$

D $22\mathrm{.}77$

E $24\mathrm{.}52$

F $24\mathrm{.}8$
