Break the polygon up into 2 parallelograms
Area = lw Area = lw
Area = 12 x 9 Area = 5x3
Area = 108 Area = 15
Area = 108 + 15
Area = 123 ft2

2. Georgia is planting daises in her garden. To buy the seeds, she needs to
know the area of her garden. Use the figure below to find the area of
Georgia's garden.
Area = lw Area = ½bh
Area = 3x6 Area = ½x3x2
Area = 18 Area = 3
Area = 18 + 3
Area = 21 ft2

3. Area = lw Area = lw
Area = 12 x 9 Area = 5x3
Area = 108 Area = 15
Area = 108 + 15
Area = 123 ft2
Area = lw Area = bh
Area = 4x6 Area = 2x4
Area = 24 Area = 8
Area = 108 + 8
Area = 116 ft2

4. Mary is planning to put carpet in her bedroom. She will place carpet everywhere
except for her closet. The carpet costs $2.50 per square foot. How much will it cost
Mary to carpet her bedroom?
