Answer:
Step-by-step explanation:
-Given that 
-We determine the z-value corresponding to the 95% confidence level:
-The margin of error is the degree of error from the real value and is calculated as follows:
Hence, the margin of error is 
4.95 x 4 = 19.80
55.29 - 19.80 = 35.49
35.49 / 2.73 = 13

The triangle is a right triangle, 9, 12 & 15.
The triangle's area = b*h/2 = 9*12/2 = 54 sq meters each end.
------------
The 3 rectangles are 10 by 9, 12 & 15
Area of the 3 = 10*(9 + 12 + 15) = 360 sq meters
-----
Total area = 360 + 2*54
= 468 sq meters
