Answer:
IT SHOULD BE 240
Step-by-step explanation:
1) Multiply 20 by 10 for 200
2) Lenght=20 so half is 10
3) multiply 10 by 4 and divide by 2 which gives 20
4) Multiply 20 by 2 because there are 2 rectangles which gives us 40
5) Add 200 and 40 which gives answer of 240

Let's just change your problem to 147 of 30%
"Of" is always equaling to multiplication (×)
Now, it would be easier to simplify
30% (147)
30% ÷ 100 = 0.3
0.3(147)
Now, we get to your answer which might be 44.1
