Perimeter of a triangle is equal to the sum of measures of its three sides, that is :
so, the three sides are :
- 1st x = 16 inches
- 2nd x + 3 = 19 inches
- 3rd 2x - 1 = 31
12 pi inches is the circumference
27.3 since 1/3 is .33333 so it would be 27.3
The slope is the change in Y over the change in X.
Slope = (7-4) / (5-3)
Slope = 3/2
