To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).
To figure out how far the points are from each other, you have to use the distance formula:



D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}




Now, the formula for the perimeter of a pentagon is
P = 5×side length
So...
Perimeter = 5×

The answer is (2)
They got $80 from the first twenty tickets. Then they got $136 from the other tickets. 136/2=68. 20+68=88
