Split up the region into shapes whose areas are easy to find. (see attached; this is not the only choice of partitioning the figure)

• The larger rectangle has area

(13 ft) × (7 ft) = 91 ft²

• The smaller rectangle has area

(11 ft) × (2 ft) = 22 ft²

• The triangle has area

1/2 × (3 ft) × (3 ft) = 4.5 ft²

Then the total area of the figure is 91 ft² + 22 ft² + 4.5 ft² = 117.5 ft².
