Agarden is going to be built in the city park in the shape of a parallelogram with a rectangular walkway through it. the garden region is shown below. find the area of the garden region by finding the areas of the individual shapes shown in the figure.

Left triangle area
.. (1/2)*(30 ft)*(72 ft) = 1080 ft^2

Middle walkway area
.. (20 ft)*(72 ft) = 1440 ft^2

Right triangle area
.. same as left triangle area, 1080 ft^2

Total area
.. 1080 ft^2 +1440 ft^2 +1080 ft^2 = 3600 ft^2


Check:
Parallelogram area = base*height = (50 ft)*(72 ft) = 3600 ft^2
