Problem $1$

Compute the area enclosed between line and the shoreline of the figure below using the offset method.

Problem $2$

For irregularly curved boundaries, the spacing of offsets along the reference line varies. Spacing should be selected so that the curved boundary is accurately

defined when adjacent offset points on it are connected by straight lines. A formula for calculating area for this case is

Area $=\frac{1}{2}[a(h_0+h_1)+b(h_1+h_2)+c(h_2+h_3)+$dots.$]$

Where $a,b,c,$dots are the varying offset spaces, and $h_0,h_1,h_2,$dots are the observed offsets.

Compute the area of the tract shown below
