3. a garden 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 in dividual shapes shown in the figure

The answer is "3600 ft²".

Left triangle area=(1/2) x (30 ft) x (72 ft) = 1080 ft²

Middle walkway area=(20 ft) x (72 ft) = 1440 ft²

Right triangle area
=same as left triangle area, 1080 ft²

Total area1080 ft²+1440 ft²+1080 ft² = 3600 ft²
Now you can also check that;

Parallelogram area = base x height = (50 ft) x (72 ft) = 3600 ft²
