There is a rule for finding perimetre of all polygons that perimetre is the sum of all the side's lengths ; according to this rule add the length of the sides of this polygon and you'll get the answer , the answer is the choice that you've written ( 2+3×2+5+6+7+9 ) or ( 2+3+3+5+6+7+9 ) both are correct because 3+3 is same as 3×2
perimetre is 2+3×2+5+6+7+9 = 35 units

X + 65 = 120
-65 -65
x = 55
Here,
Selling Price (S.P) = Rs 1869
Loss = 11%
Cost Price (C.P) = ?
Let, C.P be x
Now,
Sp = Cp - loss% of Cp
1869 = x - 11/100*x
1869 = (100x - 11x)/100
186900 = 89x
◆ x = Rs 2100
Cp = Rs 2100
I hope you understand...
It's a Right answer...

Answer:
Usual, because the result is within the range of the minimum and maximum usual values.
Step-by-step explanation:
When the z-scores is lower than -1.96 or higher than 1.96, they are considered as unusual and interesting and they are statistically significant outliers.
The Z score can be calculated by,
where,
X = raw score = 622.3
μ = mean = 674
σ = standard deviation = 26.6
Putting tall the values,
As , so the result is usual, because it lies within the range of the minimum and maximum usual values.

The answer would be 193 because first u multiply 19 and 10 and then subtract 5 which is 185 and finally add 8 which is 193.
