Answer:
triangle on the left: 6 sq ft. triangle on the right: 28 sq ft. rectangle: 128. altogether, 162 sq ft. the trapezoid is about 61.6.
Step-by-step explanation:
for the rectangle the formula is bxh (base x height). for a triangle, it is bxh/2, or base times height divided by 2. for a trapezoid, it is b1+b2 x h / 2, or base 1 (bottom) plus base 2 (top) times height, take all of that and divide by 2.

The standard deviation will be 6816.9645.
<h3>How to compute the standard deviation?</h3>
From the information given, the mean is 74000 and X is given as 60000.
P[(Z < (-60000 - 74000)/SD] = 0.02
Note that 0.02 will be -2.0537 under the normal distribution table.
-14000/SD = -2.0537
SD = -14000/-2.0537
SD = 6816.9645
