34 To calculate the property tax a city hires a coop student

34. To calculate the property tax, a city hires a coop student to determine the area of different lots in a new subdivision. The coop student calculates the area of lot 1 shown in Fig. P3.4 as 94,640 m^2. Is this the correct answer? If not, find the correct answer. Figure P3.4 Dimension of lot I in the new subdivision.

Solution

Area of rectangular part=200*300=60000m^2

Area of traingular part=0.5*200*200*tan60=20000*sqrt(3)=34641m^2

Total area =60000+34641=94641m^2

Hence the area calculated by student is correct within the limits.
