Question

Find the perimeter of a quadrilateral with vertices at L (−4, 0), M (4, 6), N (7, 2), O (−1, −4). Round your answer to the nearest hundredth when necessary.

30 units

42 units

48 units

50 units

Answer 1

plot points
N
M
L
O




then use distance formula between points
d=sqrt((x2-x1)^2+(y2-y1)^2)

i will do it between L and M
M(4,6) or x2,y2
L(-4,0) or x1,y1

plug them in the formula

d = sqrt(4-(-4)^2 + (6-0)^2
d= sqrt 8^2 + 6^2
d=sqrt(64+36)
d=sqrt100
d=10

this is one side, you will have 3 more sides to obtain
then add all the lengths of the 4 sides together and get the perimeter
