Answer: 226.5 ft²
<u>Step-by-step explanation:</u>
I divided the image into 3 rectangles and 1 triangle.
top rectangle: length = 9, height = 4 --> A = 9 x 4 = 36
middle rectangle: length = 15, height = 7 --> A = 15 x 7 = 105
bottom rectangle: length = 18, height = 4 --> A = 18 x 4 = 72
triangle: base = 9, height = 3 --> A = (9 x 3)/2 = <u> 13.5 </u>
<u>Total </u> = 226.5
Error = 1/2(Maximum range - Minimum range) = 1/2(3.2-1.1) = % = 0.0105
If p is the point estimator;
Then,
Minimum range = p - Error
Maximum range = p + Error
Solving one of the two expressions,
0.011 = p - 0.0105 => p = 0.011+0.0105 = 0.0215 = 2.15%
The answer to your Question is True. (I Believe)
Your answer should be 330! :)
