Polygon - area coordinates

Find the perimeter and the area of the polygon with the given vertices.

T (2,7), U (2,9), V (5,9), W (5,7)

Correct answer:

p =  10
S =  6

Step-by-step explanation:

T=(2,7) U=(2,9) V=(5,9) W=(5,7)  TUVWy UVTWx UTUV  a=UyTy=97=2 b=VxTx=52=3  p=2 (a+b)=2 (2+3)=10
S=a b=2 3=6
