Answer:

perimeter = (2*6) + (2*3) = 12 + 6 = 18 units

Explanation:

length: distance between (3,4) and (9,4)

d = sq.root [(9-3)^2 + (4 - 4)^2] = sq.root (6^2 + 0)

= sq. Root 36 = 6

width: distance between ( 3,4) and (3,1)

d = sq.root *[(3-3)^2 + (1 - 4)^2] = sq.root (0 + -3^2) =

Sq. root 9 = 3
