An apartment complex has a floor plan with the dimensions shown. To effectively air condition a room, 20 BTU's (British Thermal Units) are required for every square foot. Determine the minimum BTU's required for an air conditioner to cool the room effectively. Round the answer to the nearest 100 BTU's . The figure shows a composite object that consists of a rectangle, a semicircle, and a trapezoid. The rectangle is 22 feet long and 20 feet wide. The larger base of the trapezoid is congruent to the width of the rectangle. The smaller base of the trapezoid is 12 feet long. The height of the trapezoid is 3 feet. The diameter of the semicircle is congruent to the width of the rectangle. 15,000 BTU's 11,900 BTU's 16,400 BTU's 12,900 BTU's
