Answer:
11.7 is your area
Step-by-step explanation:
first, you have to add all the numbers that have the variable of a at the end, so 4.5 + 2.9 + 7.3 = 14.7, and divide by 2, which would be 7.35. then you do all the number with the variable b at the end, so 3.2 + 4 + 1.5 = 8.7, and divide by 2, which is 4.35. after that, you take both your 7.35 and your 4.35 and add them together. So you'd have 11.7, and that's your area
