240 cm^2
Step-by-step explanation:

There are 2 ends that are in the shape of a triangle
There is 1 base that is rectangular
There are 2 roof tops that are rectangular in shape.
Find the area of the triangles, base, 2 roof parts.
Solution
<em>1 base</em>
w = 4 cm
L = 12 cm
Area = L*w
Area = 12*4
Area = 48 cm^2
<em>Two Triangles</em>
B = 4 cm
H = 6 cm
Area = 1/2 b * h
Area = 1/2 6 * 4
Area = 12 cm
But there are 2 triangles
Area 2 triangles 24 cm^2
<em>Two roof tops</em>
L = 12 cm
w = 7 cm
Area = L*w for one roof top
Area = 12*7 cm
Area = 84 cm^2
But there are 2 of them <u> 168 cm^</u>2
Total Area 240 cm^2
Average systolic blood pressure = x = 130
Standard deviation = s = 6
We are to find interval that represents the systolic blood pressure of middle 99.7% of the males.
According to the empirical rule:
a) 68% values lie within 1 standard deviation of the mean
b) 95% values lie within 2 standard deviation of the mean
c) 99.7% values lie within 3 standard deviation of the mean
So, 99.7% value will lie within 3 standard deviations from the mean.
We can express this range as:
( x - 3s, x + 3s)
= (130 - 3(6), 130 +3(6))
= ( 130 - 18, 130 + 18)
= ( 112, 148 )
Thus the interval from 112 to 148 contains the systolic blood pressure of middle 99.7% of the males in the certain town
