1. **State the problem:** Ashley is installing two granite countertops. One is 3 feet long and 2 feet wide, and the other is 4 feet long and 2 feet wide. The granite costs 10 per square foot. We need to find the total cost. 2. **Formula for area of a rectangle:** $$\text{Area} = \text{length} \times \text{width}$$ 3. **Calculate the area of each countertop:** - First countertop area: $$3 \times 2 = 6$$ square feet - Second countertop area: $$4 \times 2 = 8$$ square feet 4. **Calculate total area:** $$6 + 8 = 14$$ square feet 5. **Calculate total cost:** $$\text{Cost} = \text{total area} \times \text{cost per square foot}$$ $$= 14 \times 10 = 140$$ 6. **Answer:** Ashley will spend **140** on granite.
