Which of the following equations could NOT be used to find the area of the figure shown?

• A = 10(15) - 3.75(2.5)(5)

• A = 15(10) - 2.5(5) - 3.75(5)

• A = 15(10) - [2.5(5) + 3.75(5)]

• A = 2(10)(5) + 5(3.75)

Which equation can be used to find the area of the composite figure shown?

• = 8(15) + ½(15×7) + ½(9×8)

• = 8(15) + 15(7) + 9(8)

• = 24(8) + ½(15×7)

• = 15(15) + ½(9×8)
