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.
