Fisrt is solve the distance of the segments using distance formula

Distance =sqroot[(x2−x1)^2+(y2−y1)^2]

So ditance of RS = 5

ST = 8.49

TR =6.08

The using herons formula

Area = sqrt ( s ( s-a) ( s-b) ( s-c) )

Where s s = 1/2 ( a + b + c )

And a, b , c are length of the sides

S = 9.785

Area = 14.99

this means that during the first week the prize is 18-3.6=14.4

now, the prize is marked up 20 % of 14.4! this is 2.88

so the prize later will be 14.4+2.88, that is 17.28, not 18

what is relevant here is what a number is a percent OF
