what is the perimeter of a rectangle with vertices located at (-3,-1), (5,-1) (5,9) and (-3,9) on a coordinate plane

Answer 1

perimeter = 36

it's a 10 x 8 rectangle. perimeter = 2(L+W) = 2(10+8) =36

(-3,-1) to (-3,9) is distance = 9--1 =10

(5,-1) to (5,-9) is the opposite side also = 10

(-3,-1) to (5,-1) is 5--3 = 8

(5,9) to (-3,9) is 5--3 = 8
