Question

What is the perimeter of rectangle WXYZ, with vertices W(-3,7), X(-5,4), Y(1,0), and Z(3,3) to the nearest unit.

PLEASE HELP.
A. 36 UNITS
B. 30 UNITS
C. 22 UNITS
D. 11 UNITS

Answer 1

find the lengths WX and XY. Twice their sum is the perimeter.

Use the distance formula:

WX = √((-5-(-3))^2+(4-7)^2) = √(2^2+3^2) = √13

and so on

Answer 2

Would it be A then?
